Build an auction system website

Hello bidders, I need a simple PHP, MYSQL and simple CSS auction website from scratch auction (also called dutch auction) and english auction. English Auction this is easy one. Multi-users bid item until ending. Highest bidder is winner. scratch auction: as bidster got a scratch auction and there description for it is: Scratch Auctions are a form of classic so-called Dutch tulip auctions where the price of the product is reduced the whole time until someone buys it. What Bidster created is a new version of Dutch Auctions. On Bidster´s Scratch Auctions the current price is hidden from the participant until the participant scratch the auction. Then the participant will see the current price. Every time someone scratch the auction the price is lowered. So the more people that scratch the auction the faster the price will drop. You need to have the courage to wait for a really good and low price – but do not wait too long because then maybe someone else purchase the product before you. When the price gets lower and lower the chance that someone buys the product and the auction ends dramatically increase. Auction example (Scratch auction) The market price of the product is $ 100. Starting price for the auction is $ 95 (the start price is hidden for the participants). Every scratch lowers the price $ 2.5. When the auction starts Maria scratch the auction and get the current price of $ 92.50. She sees the price in 10 seconds, but thinks it is a bit expensive and choose not to buy the product for the current price. Thereafter Peter scratch the auction and get his current price of $ 90. He also thinks it is a bit expensive and decides not to buy the product. After Peter´s scratch, Christian decides to scratch the auction and he receives the price $ 87.50. He thinks the price is pretty good, but chooses not to purchase the product since he hopes that the price goes down further before he strikes. Maria scratch the auction again and get the current price $ 85.00. She thinks it's a good price and choose to purchase the product. Then the auction ends and Maria is the winner. This site should have a 5-10 table database and should include an index file, an header and footer, a config page, admin, functions, adding item, item details, adding a image to the item, edit item, a register page, a login and a logout page and maybe another things that you think an auction website should have with a few rows with explanation code in every file like: $blablabla==1; // this code will do this The menu should be like the image below and should include 5 things: "Home", "Items", "Add Auction", "User Status" and "Contacts" -Items Page show all items image, name, description, price, time, auction type, bid button, item auction status (opening or closed) -Add Auction page should allow registered user choose english auction type or scratch auction type; upload max 4 images; description; starting price; ending price; and option each time min bid price -User Status page should show which items bidden (win, false), user own auction item (flow, sold )
