The city is not going to go for you having "control" of thier splash page. They are not going to want ad's for who knows what on their splash page.
I know I would not want that because you are offering them reduced rate internet? The city will most likely be able to get their own internet from an ISP cheaper then you would, as they are a municipality and most the time places such as Time warner, level 3 etc offer reduced rates.--
