You're already off to a good start by asking questions and looking at the options.
Driving is nice in that you would have your own vehicle, and other then the additional time involved driving each way is the most economical option.
Outfitted hunts are the easiest because with some phone calls and emails you can research things from a distance and get hooked up with some people that can dramatically improve your chances of success. But of course, that comes with a price, and like most things in life, you get what you pay for. Cut rate prices generally are cut rate services and experiences.
The drop camp is a nice middle of the road option. Less expensive than fully outfitted and guided, yet fairly easy to do from a distance.
Narrow your focus to a specific State that you would like to hunt, and then go from there. The Dakotas have some great, but lesser known, hunting. I'll send you a PM with some information on one place I could recommend.
Have fun! The research and planning is half the fun!
