yeah, ill probably mess it up, new guy here.. I'll probably gonna burn my amp if i do it

Just buy the parts and pcb, and then ask around locally for someone to do the soldering for you.
A local high school kid or college student could do it. Advertise in Craigslist if you can't find anyone.
That said, the soldering isn't trivial, because of the large copper areas on the board. There is no
thermal relief for the solder joints.
