Build a simple Mini-Site for contest

We need a mini site built for a contest. The idea is users will have to complete 4 steps in order to qualify for a prize. First they see two buttons: "Pre-Order #TakeMeOver on iTunes" or "I already ordered it" once they click either buttons, a form to upload a "proof" photo showing they bought the song will appear. Once they upload the photo the next element appears which is a form asking for their name, email, address and twitter handle. Once they submit the form a button appears that says "final step - tweet with #TakeMeOver" and when clicked allows them to tweet a link to the site with a pre-entered hashtag and @mention. At the top it will have a progress bar showing how many people completed all 4 steps and how many more we need to "unlock" the prize. Which will happen when 3000 people complete all the steps The whole thing should load within the page with ajax or something so its not refreshing. The form should validate for email and the mailing address. the twitter handle is optional field but should say in parenthesis (So @itstimwhite can follow you :) ) Attatched is a photo that details this more. Entries should go somewhere we can manually validate them. it can be as simple as a spreasheet or more complex back end panel. Once we validate the entry it then updates the progress bar. We need this ASAP.
