Well, most of the time people on here will tell you to:
'attend your local REI Club meeting'
I would disagree. Those things are filled with guys just like you. Lots of deals but little money. At least that's what I have found here in Gainesville.
If I were you I would get a free blog or cheap website from Yahoo and write down SPECIFICALLY what you are looking for and how an investor can benefit. Maybe create a similar scenario that they could expect from you. Work out things in details, not, "I find a house, we buy it and split the profits". How are the profits split? How long will their investment be out for? How much investment will they need? Why are your properties different than them looking on their own? How will the investment be housed, LLC, Corp, etc? What about closing costs, rehab costs? What protection to they have that their money is safe?
Answer these questions first, because they will be asked. Write them down in a format that people with money can read through at their leisure. A pamphlet, a website, a brochure and get it to the investors you are looking to target. Bandit signs that read "Looking for RE investments?", or mail out a letter to large land holders in your area with your info.
Basically all this can help you if the main thing is that you know what you are doing when it comes to investing. People with enough money to finance deals are going to see right through someone who doesn't know what they are doing. I would make sure you have all these questions answered before pursuing the funds.
