Build a responsive online resellers marketplace

List your items on this site and it disappears after 2 hours if it doesn't sell. Starting at 8am and every 2 hours thereafter, everything on the site is refreshed. Once your item sells if you have another item in que, it will be slotted at the top of the next 2- hour cycle. If your item doesn't sell, it's removed and will get a final chance to sell at the "last chance" slot from 10pm to midnight. If an item still doesn't sell at the last chance slot, It will not be able to be relisted until 3 days (if the user would like it relisted). When a 2 - hour cycle ends, items that were sold will indicate that it was sold. Items that did not sell will show "unsold" and will indicate that they will go to the "last chance" slot from 10pm to midnight. Eastern Standard Time. Visitors to the site will be able to view the sales but will have to sign up (free) after they add an item to their cart for purshace. Visitors can upload their item, fill out the description, and price and before it can be added to the site, they will have to create their free account. The idea behind this site is to get you to put a realistic sell now price on your items so that they will sell quick so you can get on with life. Must haves: *How many views each item has. *When scrolling down the page, the time remaining should always be visible for each cycle. *A super easy/simple menu system. *Easy to upload items - photos, description, price, condition, etc. *Items uploaded after a cycle begins will automatically load during next cycle. *On the web, items should be 4-5 gallery style with infinite scroll. *On mobile, items should be single like craigslist looks on mobile but much better looking. *Automatic loading of all items uploaded for each of the 8 cycles. *Clean and easy to use User Admin that tracks uploads, sales, no-sales. *An easy and secure payment management system to complete transactions after the sale and for uploading shipping tracking details. *An easy to use and manage admin control to manage the sites users, listings, issues, cycles, etc. *There are no listing fees. There is a 3% sellers fee. *Shipping management system connected to the USPS, FedEx, and UPS to print purchase and print shipping labels. *PayPal integration. *Credit/Debit acceptance with verification or cards and shipping address. *Search functionality. *Category tags for easy searching. *A messaging and issue resolution system. "*Pick Up Local" or "Ship It" options. The site has to be clean, uncluttered, organized, fun, exciting and look very professionally developed with simple funtions (better than craigslist and ebay classifieds). We will discuss in detail to ensure everything is clearly understood, able to be built, and easily managed. Note: There are 8 cycles per day: 8-10am 10-12am 12-2noon 2-4pm 4-6pm 6-8pm 8-10pm 10-12 midnight (last chance slot)
