Apple Mac Script / Automated helper for registering on site

I NEED THIS DONE NOW SO BE PREPARED TO START WORK TONIGHT WHILE COMMUNICATING ON SKYPE WITH ME NOW. I am trying to register a bunch of accounts on a website by tonight. I can supply a CSV file with all of the required info, such as names, emails, etc etc... Your program must run on a mac, and it must simply step through the steps on a particular site, and when it's done registering the account, it logs out and goes to the next entry.... Apple Script and Webkit approaches are fine, but it must be browser based so I can watch what's going on. You will have 2 hours to complete.
