As someone who transitioned from land ownership to lease hunting then back to land ownership, I must say that leasing, at least in Texas, can be a can of worms. Between eccentric owners and/or land managers and camp egos when hunting with previously unknown hunters, I wish you luck...but it ain't easy.
To your question, I would suggest $3,000 a gun without any infrastructure (established camp, cabin, electric, water, septic, feeders, stands) is high for 150 acres. The game limits don't bother me quite as much because they are not that far out of line with what a biologist would most likely recommend for the acreage and land carrying capacity. (NOTE: It gets real dry, real fast as you go west of Fort Worth.
Before you commit, definitely tour the property, look for sign and habitat that could support a healthy deer population. If the land manager cannot make a good case for why the property is worth what he's asking, it's probably best to take your time and continue looking. I would suspect, with the current economic conditions, we're in a Buyer's market for hunting leases.
The last lease I was on was 6 hours from my house, near Comstock, TX. Great lease: good guys, good (not great) buck genetics, 10,000 acres, 10 guns, year-round protein feeding program included, most blinds and feeders included..... but it was that 6-hour drive. We paid $1,200 a gun in 2018 to give you a point of reference.
There are some on-line resources to search for leases. That is how I found the above mentioned lease. DeerTexas.com, LeaseHunter.com and HuntingLocator.com are just a few. Unfortunately, there are far more crappy leases out there than good ones. When you find a good one, never give it up. That's why good ones are hard to find. Best of luck!,
