monies owed

[Rio Mitchell]

I was recently contacted by a company who claims that they have found $4500.00 of money that is owed to me, but they will not state where I can find it because they want 33.33%. I need the money more than they do. They claim that it is not state unclaimed funds. I have invested in several different counties in properties, and am unsure where to begin my search. I have recently sold property in 3 counties, 2 in California, and one in Colorado. How do I find this money? I have contacted the tax assessor, and no luck. Can anyone help me please?
