372913 Random # Guessing Game Site

Basically I am needing an interactive website number guessing game. First page would be a basic introduction to the game, and an entry for email and name. This is an introduction to a contest, where the user gets to guess a number between 1 and 1000 and if they guess right they win a prize. So graphics designed accordingly would be great, along with a header that will be on all pages. Next page is a large input area for their number. Once they enter the number and hit submit they will be taken to the next page. The following will be one an invite your friends page. This page will be content blocked, such that they need to fill out an offer. I have the code for that. They can also choose to skip this step and move on to the results. The last two pages are either a win page or lose page, and another field to invite friends. I can iron out details over PM. Please give a realistic bid for this.
