Create a domain checking script from godaddy bulk checker

We need a programmer to create a script that calls this page: [login to view URL] This page checks domains in bulk, it can check 500 domains at a time, you paste in a list of 500 domains, and it will check them and output the ones that are available to register. The limits are, you can only check 500 domains x times (total 5000) before it asks for a captcha, in order to continue. I think the limit is 5000 per hour, it refreshes after 60 minutes and you can keep checking without a captcha. We have huge lists of domains that we need to check, we need a script where we can paste in or upload say 100,000 domains, and the script will run, until it checks all of them. 2 solutions we have come up with. 1) setup sub scripts on a few different hosts that are all on different ip's, say 20 different hosts for example. Load in 100,000 domains, and it will split it into 5000 domains per host. The results from each host script come back to the central script and an output of the available domains after the run if each script is created. 2) use proxies or a captcha solving service. We can run multiple instances from the same script using proxies or captcha solving technology, ideally running say 100 instances at once from the same server. We need this to be efficient, stable, and very fast. We are looking forward to your solution!
