How to find wholesalers in local market (DFW)?

[Femi Salami]

I'm just starting with real estate investing and am trying to figure out how to find wholesalers in Dallas/Fort Worth? So far I've only been able to get one contact from New Western, but I would like to diversify my network. Problem is, I have no idea how to find wholesalers. I found New Western from a relative, and I've been scouring FB and craiglists. Any other places where I can find quality wholesalers? 

If it helps currently I'm looking for single family units or multi-family units, but would like to start small $$ since this is my first investment property. 

Also one more question, is it required that you pay cash to a wholesaler? I have a significant amount of cash saved up, but I would prefer to maintain my reserves for all the surprises that come with your first investment. Do wholesalers accept conventional financing options or provide financing themselves?
