I would agree with Robert that going to an iOS meetup is a useful endeavor. That said, if you are looking to truly develop an MVP, we used a shop out of Pakistan that were fantastic. They did ALL the dev work for our app, called Loyoly (you can find us on the app store here: www.loyoly.com/downloadiOSversion if you have an iPhone or iPad). Initially, we had only planned on doing an MVP, but it evolved to a full-scale application. We did it for under $10K, and that included MANY iterations.
There are, of course, issues with working with off-shore vendors. It is great when you can sit next to someone. But, if cost is one of your key variables, then you won't be able to find anyone that comes anywhere close on price in the continental US or Canada.
I can put you in touch with them if you like...just drop me a line (firstname.lastname@example.org) and I can put you in touch.
