How do you sell cannabis edibles to medical marijuana cooperatives?

I am a medical marijuana patient in California, and a hobby of mine is making delicious and potent edibles. I've heard clerks at certain clubs say that they buy their marijuana off of other patients/caregivers... one lady even told me that "theoretically you can buy a clone grow potent marijuana and sell it back to us."

Can someone please give me some insight on how I would go about selling my cannabis edible creations to clubs?
