I need a program written that will enter a person into a contest

I'm looking for an experienced programmer to write a program for me that will enter someone into an online sweepstakes. The application needs to be web-based, and I'm not sure which programming language will be best suited for the task. I need someone who has experience working with web-based application development and can advise me on the best programming language for the job. I'm looking for someone who can get the job done quickly and efficiently, so let me know what your timeline and estimated cost looks like. Thanks for your time! The information entered must go to a spreadsheet that I can access
