We have a serious shortage of ranges nearby. All we've got is Red's Indoor ranges, and they don't cut the mustard, especially at $13/hr. I have to go all the way to New Braunfels to get any rifle time in.A $10-$15 daily rate is fair to me. Annually, I don't think I'd pay much over $100, and only if it were to become my regular range.
I like the picnic area idea. That would make it much nicer to go have a day at the range with family or friends. Do make sure that you have good facilities for washing hands/arms/faces near there, so people can clean up and keep heavy metals out of their meals.
I also think the safe room and tactical pistol bays are good ideas.
One thing that I wish were improved at every range I've visited so far: decent stools. It doesn't matter how nice the bench is if you can't sit properly to fire your rifle accurately. Most of the ones in my experience have been cobbled-together 2x4 things or concrete cylinders. A decent adjustable stool would be nice.
I also like the 200yd rifle range suggestion.
