I think you are trolling. Either that or you are not hearing what you want to hear.
You have been given several answers and important questions without any attempt on your part to answer anything relevant.

I did look at your Jesus list and have reached out to them, with very low hopes of a reply. One of them did tell me to expect $16k to $32k USD
Please try to ask again, I am trying very hard to give you clear and precise answers.
Hopefully this does not come off as harsh. It's well-meant:
It sounds like there are more than a few people on this thread with some real-world experience here, and they are all saying "no" in their own way. You might be barking up the wrong tree. If it's really your dream to pursue this project--and you've mentioned already having spent some coin on it--then perhaps you should approach the power supply issue in a different way. I'm not sure how or where, but not here.
Here's my take: as someone in an audio electronics career, I can tell you there are many reasons that what you are asking for is not going to look palatable to anyone with the know-how to do it. You are re-hashing an old design, maybe making a few changes, and then calling in a "pro" to do a very basic thing. (And apparently you want to make money on it, but only pay it as a gig.) If you had a brand new, novel idea, then you might get some hits, but you don't. (and some of the responses here have rightfully questioned your use of Yamaha's IP.) So you might as well use the already-designed power supply that came with it and maybe add some better filtering and that's about it. TBH if someone wanted to make a quick buck, they should do exactly that. Hell, I'll do it. you want me to? I'll do it for $5000. Will work perfectly. And believe me, it'll be pretty damn close to the original PS.
In an attempt to go back and understand what is being asked. I must wonder if the new preamp and power amp schematic and associated posted documents for them indicates a low knowledge level person created them?
What indicates you are not experienced is that you failed to answer several questions. You failed to understand valid comments.
Your documents are all from a simulator design. Your requirements for a power supply are likewise unrealistic. You have absolutely refused to head helpful comments and go on asking for a design. You don't seem to understand what is required for a real, working design.
Now you said you have years (maybe 3) working on this. You were on at least one other site and are still at this point in the design. You seem to be setting up a kit as well. Extremely premature, given you haven't built one to test it yet. You are relying on simulator results, the mark of a complete newbie. Experienced people made comments, ignored or dismissed.
This is why you aren't any further along. My guess is you treated everyone from all web sites similarly. In short, no one can help you if you refuse to heed extremely good advice, comments and questions.

Which is right in line with expectations. About 100 billable hours at a price of 150 to 300 USD per hour. Top Quality Designers aren't cheap.
This would require a review of these actual posted documents to come to a conclusion of the talent level for the person who created them.
So it is not okay to ask for a opinion of a design and this should be considered as consultant work?
No. It is a problem you aren't forthcoming with information. This is a complete waste of everyone's time.
I answered some of your questions. You are not responding properly to mine or others. Very talented people have tried to help you. ... and failed.
When I do design work, it is a back and forth. Generally you need to fill out information from the designer you are attempting to engage. Otherwise they walk.

I thought this thread was making forward progress up until around post #33 and then the train derailed and burst into flames. 🤔😒
The old saying:
Henry Ford once balked at paying $10,000 to General Electric for work done troubleshooting a generator,
and asked for an itemized bill. The engineer who performed the work, Charles Steinmetz, sent this:
"Making chalk mark on generator, $1. Knowing where to make mark, $9,999." Ford paid the bill.
