How much does a power amplifier development cost if you order development? And which documentation package should all of this include? For example, a computer model, circuit, drawings, documentation for the board and transformer?
Do you mean development of an electronic device (of any kind) given specifications (of any kind) resulting in a design, or this and a working prototype, or this all including all tools for production involved?
Most of the time, developmet starts with market demand, an idea or solution, then a proof of concept, a prototype, a first small production serie, the final production series. The development part is a part of all costs and depends on the final total production and revenues.
For a non commercial diy power amplifier these rules do not really apply, but if you want a quotation from me, I'd say 1k for the poc, another 1k for the proto. No tools costs.

How long is a piece of string ?
If you develop it yourself then it depends on what you pay yourself.
If you employ a group of engineers it depends on what you pay them.
If you use fabricators then it depends on what you pay them.
In the DIY world all of the above just costs us time and effort.

This is not a DIY world. I had in mind the full package of documentation necessary and suitable for the industrial production of a power amplifier, anywhere in the world, even in the USA, Europe, Russia or China. I have an approximate price voiced by a well-known design bureau from the USA, but apparently, for example, according to the components used, this is their very old development, which does not even have a computer model. After which the conversation with them went wrong.

Really depends on production numbers and how complex the device is, intended markets, who you hire for design, testing, prototypes, safety certification etc.
You have really asked an open ended question, but it sounds like you have an answer for the production part.

There is production, there is a design department. The company is engaged in the development and manufacture of microprocessor equipment for testing electrical equipment. The average price of these devices is about 10 thousand US dollars. The independent start of the development of an amplifier may turn out to be more expensive and longer in time, although there will be its advantages in view of complete control of this process and introduction of operational changes.
Do you mean starting from your own circuit design, or just from your specifications?
Certainly you would want to deal with a company that is already in the amplifier business,
or you would pay dearly for their steep learning curve.

If the design company has a name and experience, then it will be easier to sell such an amplifier, since it will be possible to show this label on printed circuit boards, for example. We have a computer model based on the most modern element base, which showed the right direction and very good characteristics. But we have not yet issued design documentation.
Contract manufacturing can have many difficulties. PCB layout must be done by an experienced audio engineer.
If you are only at the proof of concept stage, there is a long way to go. Make up several preliminary prototypes and
field test them. You will find that many changes will be necessary. These changes are an order of magnitude
more costly to make during production than to make now, if they are even possible to make in production at all.

Yes, you are right, contract manufacturing can have many difficulties and pitfalls, as they are people too and can also make mistakes and make many mistakes. And we, too, may be mistaken at any stage, but these will be our “sons of bitches”.
Why not "crowd source" the design right here in DIYAudio - what with the enthusiasm and energy I've seen for anything that might sound a little bit better you'd fair more well by a longshot than expecting a random test equipment manufacturer to come up with something excellent from scratch.
Contract manufacturing and contract design are two different subjects and sets of issues. Contract design requires a lot of information to be captured. Garbage in = garbage out
I have been involved in both so have experience with both. If you want to find out yourself ask for some quotes. The term NRE costs, break even point comes to mind.

Do not think that the manufacturer of test equipment does not understand anything in audio. I myself have been fond of audio since childhood. I myself modeled this circuit. On this forum there is nothing similar to this scheme, only in general terms. This is a completely unique work, based on a new approach to the choice of electronic components to radically reduce distortion, and the result exceeded all expectations.
The term NRE stands, the breakeven point is what bothers me the most. The Japanese, for the last 30 years, have only done what has curtailed the production of audio.

Rightly so, this is all part of the product design life cycle. You could have the finest amp ever invented, but bringing it to market, making a profit, blowing a hole in your wallet is a different challenge as that is business and not engineering.
They are professionals with great experience smartly in this area, it would be interesting and useful to chat.

Chat about what, bringing a product to market? on a DIYAudio web site.
You are in Russian, you have your own market that is big enough that you do not even need to be concerned with the rest of the world. Each market has it own challenges, I am sure yours are different from mine. So much depends on your goals.

Call the developer on the telephone and ask.
Depending on how busy they happen to be in the month when your call happens to arrive, they MIGHT ask you for a 4 hour consulting retainer to be paid beforehand. Of course this would be refunded if the two parties mutually decide to enter into a development contract. The upfront payment is a how-serious-are-you type of milestone.
