I've got an idea of a program for iPhone. Decided to outsource development of its initial version to somewhere else.
Posted a project on guru.com. All bids are in range $2k-$5k (got 15 bids); some people ask per hour - chinese ask $15/hr, americans from $60 to $125 (the guy with arabic name).
Posted same project to rentacoder.com. All bidders seem to be arabic there. They ask from $1200 to $1600.
Then I've sent request to authors of similar programs in AppStore to buy their source code. People charge from $3k to $10k for it.
It seems I'll have to code it myself..
