Welcome aboard.
Ed, start looking throught the online newspapers in WY, which will lead to Yahoo jobs and Career Builder for starters. If you have any kind of a four year degree or a marketable trade, you'll be a leg up in getting to WY. I would guess that with nearly every business using computers these days and the OS's and Ap's getting more and more complex

, you should be able to ply your trade anywhere. It's just getting volume that will be tricky.
Crook county is fairly small population wise at ~8000. Ranches, a sawmill and some small support businesses. Sundance is not even the size of an unnamed bedroom community near large population centers in the Midwest and my impression is that folks there like it that way.(so do I) Nearest city of size would be Rapid City, SD at ~60,000.
If you need city populations to find a job or volume for a business, Casper, Cheyenne and Laramie would be considerations. Gillette, in Campbell county is decently sized, especially with the energy boom (although it's slowed) and may support someone going into business for themselves in computer support? Think outside the box, get creative...
I'm familiar with the Detroit area, having done business there off and on since the late 70's. I've been through the ups and downs, but this downstroke is by far wider and deeper. And nothing that our illustrious gubmint is doing is going to fix that. I think you'll agree, having folks line up at Cobo for 'Obama money' ain't gonna get it, unless you're buying votes.

I suspect it'll be a good 10yrs for Detroit to recover to pre-recession emploment, -if it can. So, getting out certainly seems like a wise move. The self reliant and down to earth attitudes you'll find in WY are in stark contrast to the entitlement and haughty attitudes often encountered in the Detroit area.
