Building(and flipping) a lot of homes, Fast. Possible in AZ?

[Austin V.]

I have a client with which I am working currently who is running into a wall as far as ability to complete construction work on time.

He has about 30 flips, predominately outside of the major metro areas of Arizona and several hundred building lots in these same areas.

Things have ramped up quickly recently and he really needs to be doing 10-15 new starts a month and complete 5 or so flips of various complexities(everything from just lipstick to complete gut jobs) in order to keep up. In short, we are selling them much faster then the limited crew and reasonable subs we have in these more rural areas of the state can get them done. 

I would imagine that some GC would jump at the opportunity to have 50 homes going at a time, However, my guy doesn't want to get raked over the coals and end up paying a huge premium to get the work done and or have quality issues with a bad GC.

If you folks found yourself as a developer in a similar scenario, what would you do?
