A good place to start looking for investors is within your own network. Start by creating a list of family, friends, neighbor's, etc. Build a list of contacts and see how far your reach is. You could then place them all onto a mailing list and keep them up to date on your real estate progress.
You could also go to a Real Estate Investment Association where you live. If that doesn't work, you could always reach out to people on BP.
Hope this helps point you in the right direction.
Best of luck:)
