What about a tourist website for your area? Given your background in retail and restaurants, you could not only list (and have people rate) hotels in your city, but you could perhaps organise retail shopping trips. Or you could list the best retail shops and restaurants near certain hotels.

Or perhaps you could open your home to a bed a breakfast, offering a tour around your city as part of the package.

Given that there's a big drive in your city in spring and summer, could you do something unique in autumn/winter to do with tourism?

Just a few ideas.
