With your expertise you may be able to help me greatly.In my mind, I am thinking that a GC would handle siding/wrap/sheathing/insulation/drywall, carpentry, demo, framing, finish installation (cabinets etc.), flooring and minor painting.I definitely want a specialist for roofing...

The way to do this with flips is to simply change your model a little bit.  

I have hear about ReStore, scratch-n-dent models from big boxes, and then of course craigslist.

This is tough but I have been examining similar scenarios and believe a compensation model that is weighted to the roi of the property makes the most sense  (i.e. a 3% payment for returning 20+%, 2% for 15-20%, etc....  

Many investors have earned there broker's license and have a superb business model offering sellers many different options to sell there house.

I then created small side businesses to increase my network and expertise, via starting an appraisal company and getting Hard Money lenders to use our company to represent them.There is now options to get into even a 20 unit apartment complex with no money, I know because I am working with a few people doing it now.

Couldn't he use an RLMO to write, what is it, 5 owner occupied loans per year (careful, I'm talking out of my expertise here)?  

Conversely, a lot of well maintained, late model, practical fuel sippers (think Corolla, Accord, etc) may bode well....Similarly, glance out at the applicants car at the showing...

Surely you can replicate the model and do a few more!

I know that there isn't a one size fits all model, but efficiency to me is always the most important; measured by how much money does my $1 dollar generate - i.e. % ROI.
