Not to blow holes in your project but it would be a huge expense to get a HD board like that and to be able to re-cope those cost would be difficult. Plus think of all the sports bars you would be competing with. I really don't see it working.
Here is any idea I kicked around for a time but never went through with it and with the advent of Expedia and Travelocity it maybe a dead idea.
Anywho, here is what you do. Apply for a IATA number, now you are a certified travel agent. Create a web site that host hotels in a specific area that is usually a seasonal place. Search for availability and good deals at area hotels and then book them for people and collect your commission from the hotels. Try to pick an area where there are limited chain hotels and a person may want a locals point of view. You work with the hotels and visitors coming in.
This is a good example of one.
