I imagine you're looking at Construct 2 because of the opportunity it provides for short development times and easy publication to the web or mobile platforms. To see what quality of work the community is capable of, I would recommend looking through the "Top Games" section of the Scirra arcade. If you want to partner with a Construct 2 developer, you will probably have the most luck in the “Game Development” subforum.

The forum moderators have more experience and probably know better what sort of information you are interested in, so you may also want to talk to one of them.
