Try obtaining a list from infousa.com. They have 4,790 contacts for hotels and motels. You can even segment it by geography, revenue and other factors for a more specified target market. It will cost money to obtain it, but I am not sure how much. It may be a few hundred dollars. After you get the list, try calling people and getting your name out there. Possibly consider sending out some emails to that outlines your services. The only thing you can really do is get your business out there so people begin to notice you.
If you have any more question please feel free to ask.
