Travel from IAH to Diboll?

I recently needed to travel from Diboll to IAH and found that there were no ubers or taxis available. Now I'm about to have to make the same trip but in reverse and I'm worried that even though there will obviously be uber drivers and cabs around the airport that none will be willing to make that trip. Im considering using a car service but that will be very pricey. Does anyone have experience with using uber or a taxi to travel out that way from IAH? Do we think I'll be ok to rely on that for the return trip?
