I think your available time should really determine your decision as well as what your real goals are. IMO, to have a decent chance at a DIY Wyoming archery bull, you need to be able to invest 7-14 days in a decent area. As a rookie to an area, the majority of your time will be spent just trying to find elk. The experience will be awesome but your opportunity for success will be 50/50 at best during your first year or two going to an area. Paying a trespass fee would typically eliminate the elk finding time but its still not a guarantee. And lastly, the guided hunts are a crap shoot for archery elk unless you pay big money. Some are great while others are not so great. During my years guiding public land archery elk we averaged 50-75% shot opportunity. That means that 25-50% of the guys paid big money to not even get a shot opportunity on a quality bull.
If I were giving a blue print for someone just getting started it wouldn't be a 1 year plan. My advice is to do some research into general areas that you can hunt year after year. Make it a yearly or every other year trip. Once you understand the animals and other hunter tendencies your opportunities will really increase.
If you really want a bull and you are just going once and don't intend on returning year after year, research and select a reputable guide with proven private land.
Good luck with your decision and sorry for rambling. Just my 2 cents
