Most flips you've done in 1 year? Where did you find the workers?

[Patrick Philip]

I think I can currently do 12/year. I really have only one reliable guy, but he works hard every day. I do some work also. 

I would like to eventually do 30+/year. It has been very hard finding reliable workers. I've even had licensed contractors flake on me after promising to give a quote.

For those of you who do so many flips that you can't possibly do the work yourself... How do you find your workers/contractors?

And what's the most you've ever done in 1 year?
