FWIW it can cost only a couple/few 100$s to hunt public as a non-res. How long it takes to pull it off depends more on the amount of time you're willing to put into it / length of trip than anything else.
Most private hunts I've heard of are about guaranteed and are 2-4 days commitment.
Climbing the walls in the Tampa metro at the moment cause non-hunting obligations are interfering with my habit in a big way this week (got out this weekend for the opener...a couple close calls but the gobblers tricked me again)
