I kept coming back to Pampa Texas. Small 20,000 person town that's growing quickly, clean, and lots of FULL hotels currently for all of the energy related fields doing work in the area. There's no card house within 60 miles. There are 2 in Amarillo within 2 miles of each other. While I don't hope to pull Amarillo customers, if I can keep Pampa people here while drawing Borger, Dumas, & Canadian customers we hope to make a go of it. I have 6 tables but plan to open even smaller with 4. We may be able to bring out extras on tournament days if need be. I have many friends who work as Traveling dealers / floors on the WSOP / wpt circuits and some of them will be coming with me to help get the place open.
Just took a quick look at the area and looks like it's pretty sparsely populated in your market. Amarillo is an hour away and already has established players. The three other towns you mention are all 30-50 minutes or so from you as well, and your local county has a population of roughly the size of the small city I grew up in back in Massachusetts (we had around 22K residents)
If you do have workers who are staying in hotels and working out there, for sure that blue collar market is one to target. Have you reached out to any hotels? Usually many of them will have a "things to do in the area" booklet or an area where businesses can put pamphlets to advertise local businesses and activities.
If that's an option you could definitely get some of those put in there, maybe with a coupon for a free daily membership and your first hour of play free or something to get some more folks in the door.
Not sure how long those workers stay in the area though, can be hard relying on so many traveling people, but the area looks like there's probably not a ton for them to do so you could definitely fill their entertainment needs.
It looks like you have some major dealerships in the town, maybe you can put together a car dealership throwdown where you invite the staff from McGavock Chevy/GMC, Parkway Ford, Parkway CDRJ, Country Toyota to compete in a tournament and provide them with some free memberships and an initial entry into the tournament (with optional rebuys if they bust) just to get them in the door. Car sales and finance guys usually love to gamble and shit talk, so can be a good crowd to get into the mix. Have a trophy and bragging rights, maybe make it a seasonal thing so they can keep coming back to compete for their dealership to be ranked #1 for that period and get some free promotion in your room?
Try to partner with some local restaurants that deliver and tie them in with specific nights of the week (on Wednesdays enjoy food from Fire Creek Bar & Grill, Thursdays is Verona Italian Bistro, Friday is La Casa Tex Mex, etc) and maybe you can get into a cross promotion where their business promotes your room and you promote them, etc.
Some sort of partnership with a local liquor store to be the primary supplier of your room and they cross promote as well.
I dunno, just spit-balling. It's tough with such a small population to depend on, but given you have no competition for 60 miles and there likely isn't a ton of entertainment in a small town, you still have opportunities to stand out and make a splash.
No reason you can't get more than 1 table/night. Maybe setup a beginners day each week where people can come in, play some smaller learning stakes (or a low buyin tournament) and learn terminology, etiquette, etc.
