Ask HN: Selling an iPhone application

I am currently bootstrapping a startup and have primarily been using an iPhone application to fund myself, but currently we need a serious investment to get going - and I'm considering selling the application.

I've got no real reason to hide any details, the application is Spit a.k.a. Speed, which is a multiplayer (non-turn based) card game available on iPhone/iPad. Its pretty much been earning a solid $60/day for the eight months.

Recently I released a patch to it which seems to have a bug I have been unable to reproduce. I feel if this was fixed and/or application improved (tbh there a lot of flaws) it could boost the income - but I quite simply don't have the time to do it.

The actual experiment was a learning experience (first time) in Objective-C / Mac so the source isn't very good - but it is reasonable.

I'm basically looking for estimated price (full income is available on request) or a place where I can sell it effectively

Any suggestions?
