dante online auction

my project is like ebay, the user who use it can sell items and buy them and search for an item . the problem that i have in my project : i can't search for items and i have some problems with the session. i need it like ebay but with online auction , i mean that every item have a countdown , any user who want to buy something he have to options buy now or buy via auction if he click the buy now button he will go to [login to view URL] which he will put his information and the address, and if he click the buy via auction button he will put his price and he will wait until the countdown ends and then automatically will goes to [login to view URL] but if another user put big price than the first user the first user must put bigger price or leave the item to the second user and so on. my project is simple but i need a more than month to complete it because i started the web design studying last week. and i need it quickly because it is my graduation project. i will be very thankful for who will do it or fix it.
