Xbox Gamertag checker

Hi, I need a multithreaded program that is capable of loading a text file with numerous amounts of accounts and checking each one to see if there is a gamertag associated with said account. Here's how the program should work. I will load a text file with accounts in this format: email:password It must logon to that account at [login to view URL] and then log what Gamertag is associated with it, if any (some have no Gamertag associated with thee email). It will then proceed to go through the text file and do the same for all the other accounts. Some things to note: Some accounts when logged on, it will bring you to hotmail's change password page, so you will have to go back to [login to view URL] to see if there's a gamertag linked to it. Also, there may be random captchas involved when logging in. Would need to see a demo before making payment. I have a strict budget of $50 for this, so if this is something you think you can do, please bid.
