I've enjoyed recording samples and playing with audio as a hobby for quite a while now. Recently I purchased a zoom h2 and the quality of the recordings are just great. What I'm curious about, is how to get my foot in the door for making money with sound design / field recordings?
I don't mean on the scale of making a career out of sound design, but how can someone get started with making money on the side -- turning a hobby into something slightly economical. What avenues of income exist? Where / who do you sell your services to? Etc.
Edit: Some great suggestions on sampling / letting the files sit there for passive income (soundsnap / audio jungle / etc). Is there any notion similar to contract work for web / code design? Sites like FossFactory allow bounties to be placed on programming requests. Do any sites host requests for sample packs?
