Haha, I had the very same idea when I needed a similar job to be done. There are many concerns though, as quick $20 could become an evening job (i.e. 3 hours instead of 5 minutes), as some extra info may arise, and you being not qualified enough may think is ‘quick and easy.’

Although in an ideal scenario that’s a really great idea, as quite many people (I believe) may be in need of such services.
