New to Wholesale in Orlando, Fl

So after reading and learning a TON of generic info. I decided with my credit being in low 600s and cash being non existent wholesaling is the route for me. I am trying to figure out how to Find sellers without spending money on marketing? I JUST DONT HAVE IT!! Find buyers In central FL How to properly complete both contracts, the purchase from seller and assignment to buyer. Any advice or local meetups would be amazing. My family is counting on me and I am tired of the rat race and have researched REI for 2 years now its time to get in before i never do. Thanks in advance!!
