Customizable widget banner - repost

Hello everybody, I want to create a user customizable widget banner with our products for marketing purpose to be posted on the affiliates sites network. We are e-commerce site with a large variety of products and we want to promote our products on the affiliates network with a commercial banner incorporated in a dynamic widget that changes products as customer interacts with it ( click left and right) . Because the target sites of our affiliate network have different formats and layouts this embedded code for the widget must be easy configurable on our site (source) by each affiliate for parameters : size ( length, width ) , category of products , individual products, number of products displayed on banner. Besides the development of the widget itself we must create the configurable admin page for the widget stored on our site with credentials user/password for each affiliate. An example of the widget it can be found here : [login to view URL] on the right part or at the bottom of the page. Thank you for your time reading this job post.
