I'm making an electric guitar with a PC mic as a pickup. What can I buy that's battery-powered with speakers for mic?

I'm trying to make it very cheap, loud enough, and self-contained, meaning the batteries, speaker, etc. would fit in the body of the guitar. Best I can think of is a battery-powered karaoke machine. I also looked into a voice changer toy (too low quality sound) and a bullhorn (too expensive). Frankly, My dream version would involve uploading virtual amp effects to a PSP and plugging a mic into it. That would be worth the price. What I'll settle for, though, is a loud enough guitar (with a body made of cardboard and wood).

Battery powered computer speakers of course. The heart of many a budget sound system
