A couple of months ago I had an idea for an iPhone app that requires a client and server component. I decided to focus on the backend development and outsource the front-end. I have posted my tender on http://www.getappsdone.com/ http://www.getappsdone.com/ and in a very short amount of time I have received several offers from shops and individuals from all over the planet, mainly US, UK and India. I have replied to every contact asking for a portfolio and I ended up with a couple of candidates. I also received all sort of prices, from suspiciously low (40US/hour)to rip-off high (> 200/h). I have based my choice on the quality of the portfolio, on the similarity of apps already developed by the shop to mine and, of course, on the overall price.
