I have my ODK Aggregrate project hosted on Google AppEngine - but keep getting locked out for 24 hours. How do I increase quota?

I have my ODK Aggregate project hosted on Google AppEngine - but keep
getting locked out for 24 hours. How do I increase quota? Would like to set
up billing but I don't see option for doing this on the appspot site where
my project is at. Do I need to migrate to Developer Cloud platform? I've
been trying to do this but can't make it happen. Help!
