Uber availability in West Houston (Barker-Cypress/Clay Rd area)?

Hey y'all. I'm planning a wedding for this spring near Barker-Cypress/Clay rd, and we are looking to set up uberevents vouchers for our out-of-town guests to use.

We don't live over there though, and I wanna do what I can to make sure Ubers are plentiful in the region before we go with that option. All feedback is welcome and helpful.
