Where's my boy Musiqsoul when I need him! LOL! But I take a stab at this.
I guessing that you going to use the PC to put everything together right? If so then you may need a mixer for your mics and board to record through the PC or even can go as getting a digital recorder and run everything through that if you think your computer can't handle it...Roland and Korg has pretty good recorders at affordable prices so check their sites out and see what you come up with...as a matter of fact, don't have to be the exact amount but how much you want to spend to the studio? That could help us a bit without going over your budget.
