Ask HN: Abandoning app alternatives?

So we're a little start up and we've got a couple of apps on the App Store that are selling just about alright (a few hundred $ a day on avg). Due to other commitments, we can't really spend much time over the next 6 months maintaing them and adding features. Seeing the apps just rot for such a long time doesn't seem right and we've been thinking of possible alternatives.

One option would be to hand them off temporarily for a certain % of the profit to someone who's got free time on their hands and wants to work a something that's being used by people. I'm not sure how realistic that is or whether we want to do it, so any thoughts on the subject would be greatly appreciated.

Thanks.
