We are developing a website for a client, but our developer has taken it as far as she can. The website is for a gift card swapping company, wherein they buy, sell, and "swap" giftcards. The client wanted this to work someone like eBay in the sense that users can log in as a member and create a profile, browse giftcards and either purchase/sell directly to the company or swap with other users using a messaging system. Our developer has already developed about 80% of the site, but is having trouble with some of the swap and sell options. The client has provided an extremely detailed spreadsheet on how he would like it to look and function, which I can provide. There have been some minor changes, but overall it is the same. The website was developed using Wordpress, but other applications can be integrated if necessary to finish the project.
