Ask HN: Best outsourced web app developers?

I have an idea for a web app that I would like to see developed from start to finish.

I'm looking for a reputable company that won't steal the idea and that takes pride in their work.

The idea is relatively simple but of course the devil is in the small details.

I'm prepared to fully fund this myself no worries there so I'm not looking to give up any equity in the idea.

As a side note, I'm curious if HN'ers think it's a good idea to outsource the whole ball of wax or if you think it could lead to problems down the road?
