Using a pocket listing to wholesale a property....?

[Patrick Williams]

I am a new investor and have found a property that just might have enough juice to wholesale using an agent because I know a stud who can sell it fast. I have negotiated a discount on his commission with the notion of doing plenty of business in the future together. The house is currently occupied with tenants which I am using to start with 60 days to close since that is the notice period for California and I'm tacking on an additional 15 days....

I'm getting the property under contract soon. 

a) Is it legal in California to fill out a purchase agreement with the seller with the intention of using an agent to find a buyer and 

b) Can I use a closing process identical to a typical simultaneous or double wholesale close?

I know this is sort of a newbie question, please respond in layman's terms haha.
