Hi Gary Welcome.
As you know this is a very hot and tough seller's market. There is a lot of competition but that doesn't mean there is not opportunity. I would recommend that you listen to a minimum of 100 podcasts from each of the top 5 wholesaling ones out there to get an idea of what needs to be done to get on their level. Some to mention are Biggerpockets, Flip2Freedom, Wholesaling Inc, Simple Wholesaling, Flipping Junkie, and many more.
Attend many of the meetups in LA geared towards wholesaling, there are several. Get a simple business card (don't spend more than 2 minutes creating one) and introduce yourself to everyone and give them your elevator pitch.
Once you get the idea and scope that's required to be successful at this in this market, go knock on doors and cold call as many sellers as possible and get comfortable being uncomfortable and being told no. If you have the budget to start a marketing campaign, pick a list, and hit that list 5-7 times. On average it takes a wholesaler about $5k-$8k to get their first few deals or pounding the pavement 40-80 hrs a month.
I hope that gives you a good rundown and enough to spark your interest. There is a lot of money to be made you just have to want it bad enough.
