Since the receiver is the only part considered a firearm what if I did this. I pay for an ak kit have someone els who knows what they're doing assemble everything EXEPT the receiver and then I just buy a receiver through a ffl. Thoughts? They technically would not be giving me a firearm right?

because ATF has already issued a letter stating that just because a bare receiver is a firearm, turning that bare receiver into a working rifle is considered "making" or "manufacturing" a firearm, depending on one's status (whether or not you're an 07FFL). In other words, either you have to do it, or an FFL has to do it.
That said, as I mentioned above, you should probably look further into what constitutes an AK build, because you seem to be very confused over it. Like ak_ said, you have to rivet trunnions and the trigger guard into the receiver, then press in the barrel, and populate (if you didn't populate it before pressing it in). You either have the tooling to do this, or you don't. If you don't, you're going to need to either buy the tooling and become familiar with its use, or pay an 07FFL to build your rifle for you.
Or find someone in your AO with the tooling who's willing to show you how to use it, and allow you to use their tooling to complete your gun. But you'll be doing the work in order to stay legal.
