Update database with property data

Using a list of properties generated by a web form, find url for each property, pop into that url, scrape property data (address, # bedrooms, square feet, etc.). Test for [uninsurable] -- if not $uninsurable, open database to see if property is already in database. If so, update database with $property_data from above, else add new record to database and update with $property_data from above. Lastly, create java script to run on Windows machine which automatically runs this whole process 3 times daily.
