If you want to start a business cleaning and hauling trash from foreclosure/ REO properties, try contacting the Acquiring Financial Institutions of failed banks... go to the FDIC's website to find preliminary contact info for the Acquiring Financial Institutions. Remember, you DON'T want the failed banks' info, but rather you want those organizations that are now handling their real estate assets... Lot of the big property preservation companies that handle the big contracts for these financial institutions are swamped ... they need the smaller foreclosure cleanup companies to help out. But make sure you have your ducks in a row to get these contracts and subcontracts (proper license, registration, insurance).
Good luck!
