Matt, if you are looking to find wholesalers, you might start by calling people who use bandit signs. Most of them are wholesalers looking to reel in cash buyers to add to their list.
I would recommend starting out as wholesaler yourself. You minimize the risk to yourself or your business, it's fast cash, and you don't need to do a lot with any properties.
Usually wholesaling is the gateway to rehabbing. Also, rehabbing will suck the life out of you. You might make $30K, $40K, or more, but it might take 6 months by the time you get the house rehabbed and get it sold.
I would do what I did, and get Cameron Dunlap's "Fast Cash with Foreclosures" system along with his iFilp system. It's about $1,000, but it is an online machine that gives you every tool you need to get going including: GUARANTEED funding, a list of cash buyers, POF Letters, "Wet Funds", your own cash buyer website, your own seller website, bird dog website, and much more. Also, when you pay the $1,000, it's credited to you when he funds you 1st deal. He charges 2 points for the funding, but that is nothing compared to hard money fees. So as long as he funds a deal for you, it's like the system was free.
That's just my advice, and also, I wouldn't risk your own money initially if you don't have to. Here are Cameron's top 10 mistakes in Real Estate:
1. Originating mortgages in your name
2. Locking your money into a deal
3. Not bringing in enough leads
4. Inadequately pre-screening leads
5. Not choosing an exit strategy before making an offer
6. Funding a deal when you don't need to
7. Needing to do and understand everything yourself
8. Not delegating what keeps you from making money
9. Not becoming a transaction engineer
10. Letting someone convince you you can't do this
