Just started my property management company (Erdoglyan Property Management Group) Would love if someone can help me out with leads, I can offer a referral fee ranging from $300-$1,000. I also Know an agent that offers 3% commission. If interested give me a call or respond to the message would love to partner up with some smart investors. 

You already may do these things, but here are a couple ideas:

1. Talk at a meetup in the LA area
2. Facebook ads
3. Search profiles on BP of LA-area investors and message them
4. Network with agents that are investor agents
5. Become a NARPM member - many investors start their search there.
6. Network with contractors, ask them who they know.

Get hungry, network like crazy.
