Dynamic Banner Design

Hi, I want a banner for my pet supply [login to view URL] should be dynamic and all links to different section of my store. Banner should display different images and text and all can be changed from a file. I had a very bad experience working with some guys who won bid, work for 1-2 days and then got another project and left in between. So please if you can't complete this project then do not bid on this project and waste my time. To get an idea you can check banner at http://www.macys.com. Max budget - $30 Thanks
