Create a script to bulk check 500 domains at a time for availability using Godaddy's bulk lookup

I need a web hosted script created that can bulk check 500 domains at a time through Godaddy's bulk lookup tool. Link: [login to view URL] We will feed the script with a list of domains, usually hundreds of thousands at a time. The script will load in 499 or something at a time and then record the available output. The tool can only check the specified TLD's on the page, so we want the script to filter out any TLD's that do not appear on that list. So it doesn't cause any issues or screw the process. This script will need to have proxy support as the page will request captcha after 10 requests at a time from the same IP. We will provide hundreds of private dedicated proxies for this. We would like to have a basic interface created using these theme: Link: [login to view URL] We will purchase this for you ^ We'd like the interface to have these features Simple Uploading function Input/save proxies History - record previous projects and provide links to download the output Once this is created, we'd also like to create the exact same script for these 2 sites as well. [login to view URL] (200 at a time) [login to view URL] (50 at a time) We'd have these 3 scripts incorporated into the admin interface, and allow us to use either of the 3 checkers for the type of domains we need to check. Basically all 3 URL's check different types of TLD's/domain extensions. But for the last 2 (Onlydomains and Netim) we dont need to incorporate TLD filtering, because they can check ANY TLD. This project will lead into ongoing work.
