Coding a website

The website itself is fairly simple, but the backend is a little more complex. Basically I'm a buyer of virtual goods, and I sell with various other virtual goods. I was thinking of using some sort of a wizard like the following : [login to view URL] On the home tab will be a few reasons why they should sell to us. They'll click continue to enter the amount they're looking to sell, then hit next. The second page in the path will give them a quote (this quote varies based on a rate that fluctuates daily, and on the amount that they're selling to us), or other payment methods. From that point, they can submit their basic contact info for us to contact them (along with what they'd like to be paid with) or they can hop on live chat for immediate service. The final tab will offer a quick summary, with a link to an optional registration system. This website is designed to be minimalistic, and as I'll be filling in the content on the wizard, nearly all of your work on this project will be the backend. I require the following things: 1. A page that I can view that displays all sales with various sort options (date, amount, userID, IP, saleID). 2. A secondary page where I can edit the various quotes (I don't want to delve into the code everyday). If the sale amount is between 0 and x, then offer a. If they're selling between x and y, offer b. etc. 3. An optional registration on the final page of the wizard, and then a login system for the user so they can view their previous sales. That should look something like the following: [login to view URL] You do not need to make all of this yourself, feel free to take templates online and borrow. It all just needs to look VERY professional and nice.
