Create Joomla Banner module

Looking for a Joomla expert to complete a banner module for a real estate website. Must have ability to work on Joomla. I have a full-time programmer confirming it will take less than 1 week I pay him $US230 per week so do not bother bidding higher. The back end of the iProperty software will have a banner module where admin is able to view all banners that are being displayed on the website: You will be required to set up a front end uploader system (PHP is fine) where users can upload the banners & make a order and then submit it to be stored in the database. Order will be able to be accepted by admin in Joomla before being accepted. Invoice will be generated via a system that is already built and the order info just needs to be sent via xml. In the back end admin is able to set the price for each banner position. NOTE: You do not have to organize the banners to be displayed on the front end. The banners will simply need to be stored in the database and our in-house coders will code the website to grab the banners that are stored in the database.
