Database creation

I would like someone to mine [login to view URL], obtaining all of the profile pages placed into a database. For instance, if you click on Arizona, and then go down to "search using these criteria", you will get a return of ~4800 results. Under the "name and trade name of firm field, you will see a link to the companies profile. [login to view URL] is a random example of a page returned. There are two ways I can think to gather this data: one is to use a brute force query DUNS=000000000, DUNS=000000001, etc. The other is to automate the form filling out procedure (using something like selenium) to grab the currently existing pages with a valid DUNS number, and then use that generated DUNS list to grab the pages themselves. I would then like each field in the page (email, phone number, ownership and self certification, etc) to be entered into a searchable database.
