First, this is a great problem to have! Enjoy it. More to the point, is there a business entity that owns the app? If so (or if you can create one), giving some equity to someone in exchange for helping you complete the app (either the current version or the next) is a way to pay without any cash outlay.

Last... definitely not accusing you of anything, but I was just musing on the fact that this would make a good marketing campaign: young upstart with too much success and not enough capital -- it's like a cinderella story ;)
