While I totally get the thought behind stacking functions and trying to get a "yield" from the hunters, I think that prioritizing your needs would be helpful.
What do you need most: The labor/money from the hunters or the deer gone?
If it is most important to solve your deer troubles, making the proposition less attractive for a hunter by charging money or a day of manual labor for access to your land seems counter-productive.
Other things to take into consideration:
1) Where are the hunters coming from? If you are close to any sizable urban/suburban area, you might try putting up your contact info or a simple flyer at gun stores, outdoor stores, sporting goods stores, etc. Keep in mind, urban/suburban hunters that have to travel to get to you might be willing to spend a few dollars for access to your land, but are probably "time-poor" when it comes to swapping labor for hunting permission. If you have
local businesses that provide food & lodging, see if you can get discounts for out-of-town hunters coming to your land. Hunting season is often a dead spot in the hospitality year and local businessmen might be glad for the business.
2) Are there any Fish & Game clubs in your area? A state rifle & pistol association? Other social organizations with large memberships? Offering discounted access to members of organized groups has a two-fold benefit: It gets word of your property out to a larger group of people much more quickly and it has the built-in security of peer pressure where individuals are less likely to do something that will screw things up for all their buddies. You can also dole out blocks of time for each group and let them deal with assigning individual day access, lessening your time involvement.
3) Many states have 'Youth Hunting Days' - You might consider donating use of your land to a local youth group. You get exposure and the possibility of future customers when those youth hunters come of age.
4) Have you thought about the possibility of actually trying to make this a profit-center for your land? You don't mention how much land you have, but I know a couple of people in upstate NY who have 20 acres or so that manage to pay the taxes on their property with hunting leases. Their only investment was clearing a few trees and planting some food plots.
5) You may not hunt, but you're obviously not against the idea. Seek out the advice of the people you are trying to attract.
Permaculture teaches us to listen to the land and the plants, why not listen to the hunters if you want to make them part of your system?
6) One word of warning: Talk to your insurance agent. Make sure you are covered. Having hunters sign a waiver is a good thing, but unless it's been prepared by a lawyer there are probably potentially expensive holes in it just waiting for another lawyer to find. Unfortunately, this is how the world works these days.
