Writing your own offers in CA without Realtor license?

[DG A.]

Hi BP-Amigos, 

I'm working with my dad on a couple of leads for a flip. We've got 2 different home owners in a distressed situation that we're doing some verbal negotiation with. I've worked with a lawyer to write offers for me before, but it costs about $500 per offer.   :O

Here's my question: 

Is it possible for me to write offers to these homeowners myself without a real estate license? I've searched the interwebs pretty hard, and I can't seem to come up with a "blank" version of the standard California Association of Realtors "Purchase Agreement."

Does anyone have experience in this area? Are one of us required to have a realtors license to write an offer in California?
