JV funder looking for deals nationwide

I recently left a demanding full time job and am now doing consulting so I have more free time to invest in real estate. I'm most interested in funding deals with other investors who are better at finding deals (I'm better at finding money). I'd particularly like to work with residential land flippers nationwide who need funding for 30-60 days. Profit split would depend on the deal but generally looking for 50/50 and a minimum return. 

Where should I look for these kinds of investors and what red flags should I look for beyond the regular due diligence (title, survey, flood zones, etc.)? Anyone else doing these types of deals?
