Looking at buying land for a lease.

Folks, please forgive my ignorance here but I'm not a hunter so I figured I'd ask the experts... My father is a huge hunter and I've always wanted to do something for him so I'm looking at purchasing some land and converting it to a hunting lease. Before I do I have a few questions...

1. Is 150 acres and acceptable size for a hunting lease?
2. How many hunters can 150 acres reasonably support? (My guess has been my dad and possibly one more)
3. The property I'm looking at has frequent whitetail, turkey, and the occasional bobcat from what I can tell. It is also in elk territory according to the state. Is this good?
4. If the property can support more than one hunter how much would be a reasonable price to charge for access to this kind of property? (Please, no ridiculous $1 per acre comments. I may not be a hunter but I know better than that.)

I'm hoping I can get this done. My dad would absolutely flip to be able to hunt a private rather than trying to scrounge public lands but he always said was much harder to do.

Thanks to anyone willing to help out with some information.
