Here's the link to the landowner list for the E-plus system. It has all the landowners who get tags, how many they get by sex/archery and a contact number.
Here's how it works. When a ranch signs up for the system they have to designate whether they are ranch only, RO or unit wide UW. If they designate RO, their tags are only good on the ranch, not the surrounding public area and they can post their land no hunting. If they designate unit wide the tag is good anywhere in the unit, but they have to let others hunt their land. So big ranches with lots of tags lease their land and accompanying tags to outfitters who run the hunts and designate RO so they can control the hunt. That's why you can see people advertise guaranteed tags and hunts in NM. These will not be for sale to anyone who doesn't book a hunt with an outfitter on private. Little ranches with just a few tags typically either use the tags themselves or sell them and designate UW. These tags are priced so high because the outfitters buy them and use them on private land they already have leased where they can sell a hunt for $7500.
It sucks, back in the day you could buy a landowner tag for 600-700, now they start at 2500-3000. An outfitter who already has a ranch leased can afford 3k for another tag, cause after paying a guide and food for one more hunter he's looking at 3k profit, or 100% return on his 3k investment. Stupid economics, these guys are driving the prices up. Your best bet is to start on that list with all the UW tag holders with the fewest tags now and see if you can sew something up for next year. Maybe you'll find someone who needs cash now.
Sometimes you can find last minute deals on Craigslist too when people hold out and nobody buys their tags.
Good luck.
