There's a chance that there might be some sort of internet source, call it FSBO (for sale by owner) out there. Otherwise you'll have to either beat the (sage)bushes in person or find the FSBOs in newspapers.
Zoning is variable by county, some are tougher than others. Raising crops for food in Wyoming's climate certainly would be more challenging than in most other states. Growing season is short, rainfall not abundant (Sheridan County about 13"/yr, Washakie about 9"/year as examples.) For water, it's mostly there, wells vary in quality. Some have to go pretty deep to get decent drinking water. Crops can be ditch irrigated, if you get a place that has ditch rights. These are variable as far as how much water you can count on, early filings (125 years or so ago) can cut off downstream users. The city of Sheridan found that out a few years back, a ranch upstream had better water rights than the City, the ranch's filing had predated the City's by a couple of weeks, this done during the 1880s and not "discovered" by the City until it had to do water rationing during a drought year.
Finding a trucking company within fifty miles of the house will be a snap, unless you live further than that from town. If you can stand a job which is not straight trucking, driving jobs in the oil and gas patch abound. Class A CDL plus work outside the truck, pretty good pay. Schlumberger is a big outfit, sort of like Halliburton but better, they shower money and benefits on their hands (drivers.) That outfit really does not care how much they pay their drivers, DOT times are a factor but your wages are not. Only thing is they want 11 days on and 3 days off, and pretty urine. $60k/year and home every night. Free medical advice, free legal advice, company stock (good $ stock) at greatly reduced price, and even $30/month toward your family's health club membership (you are out on jobs, so can't take advantage of this....)
Privacy can be had, with expense. Real estate is pretty high in many parts of Wyoming. I've never seen much of people living the rugged lifestyle in Wyoming. People used to live in teepees some around Wilson a generation ago, but the back-to-nature lifestyle seems to never have caught on strong in Wyoming as compared to states with a more moderate climate.
There's a couple of key things here: the climate is a bit tough, for one thing. For the other, Wyoming has a history of exporting (voluntarily) its unemployment problem. It has always been a hard climate, boom-and-bust place, with little to hold people when the good times run out, and a poorer place than most to live without cash income.
