Digital Signage Graphics / Template Creation

We are a digital signage integration company that is looking to bring the graphics, design 'in house'. Currently the software vendor we use provides this service. Basically, we gather creative content (photos, fonts, colors) and need someone to produce template using digital signage software (we will provide). Creativity and graphic content a must. The ideal contractor would have already designed digital signage templates, understands readerboards, way finders (touch screens), meeting room signs and integration of CMS (contact management systems...MSExchange) and RSS feed into the template. We are a little unsure on how to summarize this; so if you have additional questions or clarifications, please ask!
