Create an item posting system

This project will require 3 main things. A.) user can post an item to their feed or in a group they belong to. B.) the item is submitted via a form that includes submitted information, like location, price, timestamp, name, details, ect which is stored in the sql database. C.) a page that has a sortable list of items with images that link to the item post. I am very familiar with these types of system and just don't have the time to create it. It uses an existing database, and will need a few tweaks done to the status form to work. Bid on what you will accept as a price to perform the work. Messages to increase costs and project time are not accepted. Should be done within 3 days.
