Texas Panhandle Native Grassland available for Quail lease this season

I am offering up acreage in the Texas Panhandle, just outside of Amarillo for quail hunting this season. I am looking for a max of 10 hunters, for anywhere between 6k-12k acres. The lease price is $9 - $12 per acre. The price is lower for leasing the whole acreage and higher if leasing a smaller portion of acreage. 

This is a working ranch and there are no livestock present at the leased hunting pastures though some are present in other pastures. There will be other one-time Mule Deer Hunts on the land (one time, pay per head); otherwise, there are no other uses except for grazing. 
We have done a quail survey this year and found about 6.5 birds per mile with coveys of both Bobs and Blues.

Limited Camping could be allowed but impact must be minimized.

We have lease templates available but we would need to determine the number of hunters, size of acreage and other terms to certify the document. We will also require liability waivers for everyone present on the lease.

Hunters must be neat, clean and respectful of ranch operators, gates, roads etc.
