Or elance for small/quick problems.

What I'd do is white-label it and make it available (revenue share) with communities/networks. e.g., say ForumX always has newbies struggling to install their code and get things working, and a voluntary support forum isn't always ideal. So they run paidsupport.forumx.com (or whatever) as a marketplace for cheap installation help. Scrape x% from the transactions to split between ForumX and WageMachine.
