Wi-Fi Advertising Platform

I am looking for a Wi-Fi advertising platform to be used mainly in a hotel with over 200 rooms and conference facilities. We already have a Wi-Fi network in place and the system should work with Linksys routers. The platform can be used in restaurants, airports and cafes where users have access to free internet access via Wi-Fi. Moreover, the platform should accept and deliver advertising content in various formats (i.e., banners, flash, video) to be accessed from a computer or any Wi-Fi enabled device. The Hotspot advertising solution should include an Ad management/reporting facility and enable delivery of relevant ads in the following options: 1. Flash or Video On screen prior to giving users Internet access over Wi-Fi. 2. On screen after authentication. Can be either Flash or Video 3. Display of ads on the login page 4. Horizontal or Vertical Banner ads on every web page displayed. For this project, I need professionals with profound knowledge in the Proximity Marketing space as well as excellent Design and Software development skills. For all bidders, a portfolio of your work is required. I'm very open to ideas and thoughts that you may have, particularly on hardware specifications. I'm already managing several Wi-Fi networks using Linksys routers. As it is, I would be very happy if you can provide us with a plug-and-play solution. You can contact me for more details and clarifications. Timeframe for delivery: To be discussed. Looking forward to your suggestions and proposals.
