By "foreclosure cleanout work" I assume you mean cleaning and fixing up homes which have gone into foreclosure?
The best way is to contact the local real estate agents who are listing several foreclosed homes. From them you will find out if the bank has a crew already or, if they are open to local craftsmen. Then it would be a matter of convencing the listing agent that you should be their 'go-to-guy'.
I will be happy to provide you with a list of such agents for this area.
