Waterfowl clubs can fetch a high dollar, but you get 3 and a half months.
For big game I am not thinking people would be willing to lay more then around $1000 per year. Because for that price, I will just go to idaho or Montana.
It's going to take a ton of capital to get a sizable amount of land tied up for hunting. Statistically something like 80% of deer hunters are rifle hunters. I would never pay $1000 to share a lease with other people for an 11 day rifle season in eastern Washington. Elk, your going to be limited by the tags. I wont pay to shoot a spike. I might pay to shoot a big bull.
In summary, I don't see it working in Washington. For $1000 a year I can apply for Wa Id, Oregon, Nevada, and Wy, and probably get a decent tag each year. Washington doesn't have the quality or quantity of big game to comand much for money.
