Welcome to Utah County!
You are correct, there are a handful of indoor and outdoor ranges here in the valley, some of them are...
* The indoor range at the Orem Fitness Center.
* An outdoor range near Squaw Peak operated by Provo City.
* Discount Guns and Ammo in Provo.
* Rangemasters of Utah in Springville.
I personally do not like indoor ranges, and do the bulk of my shooting in the West Mountain area near Payson.
