Putting a house on the MLS under contract

[Account Closed]

There is a house on the MLS that I would love to wholesale out to a potential investor. The problem is....I don't know how! The home isn't foreclosed or anything, it's owner occupied, just a normal listing. Do I contact an agent and put an offer in on the house? If the offer is accepted what happens next? Do I present my own purchase and sale agreement and put Cesar Ramos and/assigns to in the name of the buyer? And then go and present an assignment contract to my cash buyer? Or is there a completely different method to all of this?
