The problem ISP Finder solves

This is community project for making a database of internet service provider categorized by postal code. The project stems from my personal terrible experience of finding local providers, since local providers don't have very big wallets, they don't spend on well advertisements, some of them don't even have a website and some others just don't appear on search engines. Hence, this database can be one-stop-shop for finding all providers operating in an area.
