I have contact with a large number of Xenforo administrators/webmasters and there is one common theme that constantly comes up: how to find trustworthy quality developers.

There are always a ton of projects that admins need to have developed, but projects fail rather than succeed because there are just very few quality developers around that can also be trusted.

The quality developers that are there are fully booked. I have several working on my projects. Most of them I know from vbulletin.
I try out new developers regularly but that mostly fails. The developer often does not deliver, becomes unresponsive or is not able to deliver. Before or after getting paid. There are a lot of hobby coders around that offer code quality that you simply should not run on your site. Especially not on a medium/big board.

It's not a matter of not being willing to pay a reasonable rate. If you need quality then it's extremely unlikely that a developer with a low ball rate is going to deliver that....
