RSS templates in Flash, for sigital signage

I am looking for someone to develop Flash-based template for full screen, landscape mode digital signage displays, that will query and display external RSS or XML feeds dynamically. There should be scripting to "sniff" at regular intervals for refreshed data. The primary application is for news, and I need option to display headline only, or headline and first paragraph, as well as options for source and time/date. There should be a default background image but an option to select a background jpg or jpeg from a PC directory to change from the default background The font attributes should have variables such as bold/italics/size. There is a strong opportunity to have recurring business as clients request custom backgrounds.
