Need contract templates for flip partnership and for GC

[Jeremy Fruechting]

Does anyone have a quality (attorney reviewed) contract you have used for a flip partnership that you'd be willing to share? Or do you have a resource online you like to use (for purchase)? 

I also need a GC contract. A couple houses under rehab are with a GC who had his own. I've got a younger GC who wants to do one house, but I'm going to take the opportunity to develop my own contracts for future use. 

Thanks in advance!
