Demographics Software Needed -- Cross references demographic information with homes for sale online

I am looking for a way to automate the search and cross referencing of housing for sale by owner and/or expired MLS listings with relevant criteria, such as owners who have recently applied for bankruptcy, a divorce, or the passing on of a spouse (recent death certificate connected one of the owners of the home). In particular, we are currently focused on high end homes in the Florida market. If you have additional suggestions of data which would be useful to be able to cross reference, I am certainly open. You would be hired for your knowledge of the industry as much as for your programming skills. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
