Am I required to get a GC license as a rehabber?

[Robert Freeborn]

I just finished my first flip and am in the process of selling it.  I'm already looking ahead to my next flip.

For the first one I was working full-time at a bank, and didn't have the time to organize it 100% by myself, so I hired a GC.  

I'm considering options for the next flip.  One of which is to work on it full-time myself.  I would hire out the skilled labor, but do the majority myself.  I would also consider paying myself a wage from the rehab budget, either as an individual or through a second company that I make for the purpose of submitting the labor invoice.  

My questions are as follows:

1) Would I need to get a GC license for this, especially if I own the property?

2) Would, or do you, take paycheck for labor when you do rehabs?

Disclaimers: I live in WA state, and will be getting my RE license next week.

Thanks guys!
