^As in, you've been sending PMs to people asking them to voice act for you? Another good method, one that's WAY underused in my opinion.
Audacity and a better microphone will do wonders for improving your sound quality. The other thing I can advise you to do is limit background noise as much as possible. How to do that? Well, get your mic as far from your computer tower as you can (you'd be surprised how much noise that fan really makes). Ask your family to keep it quiet while you're recording, or do it when they're not home. Keep any pets out of the room. Put the mic on your desk rather than holding it, as even slight movements jerk the cord and can cause popping noises. Use some sort of pop filter (even a Kleenex stretched tightly in front of the mic will help) to prevent hard sounds such as "b"s and "p"s from creating popping noises. And check your volume... if your voice is too quiet, you'll have to raise it in post-production to make it understandable and background noise will be intensified to uncomfortable levels. But if it's too loud (a big problem when recording shouted lines--back WAY away from the mic to solve this), the audio will "clip," which sounds just as bad.
