The reality about real estate agents, in my experience, is that they do not really give much time or attention to anyone who is not actually here. Trying to deal with them on line or even by phone was terribly frustrating for me in '05. It's a seller's market here right now, and they can afford to ignore those who might be just "looking." It's poor business, and will come back to bite them, but there it is.
I suspect that some of the FSW folks now in Gillette and Moorcroft can help you in at least talking to them. Moorcroft would be a good place to look, I think. Prices in and around Gillette are pretty high now, even when there is something available. Newcastle, where I am, is about an hour or hour and a half from Gillette, depending on weather and how fond you are of paying for speeding tickets. <G> Prices are better here, and it's a nice friendly town. Might be worth looking at. I'll be glad to help in any way possible.
Call and talk to Vera at Home Place Realty. http://www.homeplaceusa.com/ Tell her I referred you to her. (She knows "MamaLiberty) She helped me buy this place and was terrific. She only lists things nearby, but she is a full realtor and can help you with anything that is listed.
Another problem is that not everything is placed on the multiple listings. Many realtors here maintain some exclusive properties, and many of those are the real "deals." You just have to be here and make the rounds to find them.
The best idea, far as I'm concerned, is to buy or rent SOMETHING, anywhere you can and GET HERE. Once you are here you can look for that perfect place you really want.
Good luck!
