Domain Name Registration Script & API Integration

I am looking for automated multithreaded server-side domain registration script to catch domains. It needs to work with a registrar using their API interface(will be sent directly to the programmer). The script should attempt to register a domain name using the API's starting from a specified time and should work till a prespecified end period (or should stop when the registration attempt is successful). I would need proxy support added to this script to go through a different proxy IP for each availability check. I would like the option to set the amount of availability checks per second. After the domain check finds the domain available it should then use the Registrar API to register the domain. There should be no issues even if multiple jobs are running at the same time. The script should have a web interface to allow easy access to run. Recommended project for someone who understands various domain registrar API's, has done similar scripts before, and knows the details of how the script needs to function. API documentation will be provided. Please bid only if you understand the nature of the project. Any email thats says "I can do this job" or something similar will be ignored. Please email me your experience with this type of job.
