I'll be a little more decisive than most of the other posts in this thread.
DON'T DO IT
You are robbing yourself of potential jobs by moving to a rural area. What happens when the company that is hiring you decides to go through a downsizing (I mean, rightsizing) effort, and decides that you are redundant overhead? What other similar type jobs for the same pay are available in that rural area? My guess is few to none. So, let's say that theoretically you can then find a company where you are currently that will hire you and pay relocation (Not very likely in more urban areas, they don't need to go outside their urban area to find warm bodies, but for the sake of this argument let's say that's the case). Now you have to move yourself and your S.O. another 700 miles just to end up back where you started. That's asking a lot of someone, to relocate twice in a relatively short period of time, with no regard to their career, etc.
And the payoff to this is, what? A little bit more money, and a *potential* bonus. My experience of potential bonuses is that they never live up to that potential. A bird in the hand and all that. Plus, you get a title. There are other ways to get that title. I find that working for a smaller company, you have more opportunity to get a good title, especially if you ask for it. Then you can parlay that title into a better position at a bigger company, since most HR doesn't check how large a company you came from. If I have a "Director of Information Technology Engineering" title from a small 50-man shop, I can pass the initial sniff test for the Director of IT position at a 1000-2000 person company. Once you get to the inital interview, then your personal skills come into play. You get the job, but your title opens the door.
But hey, that's just me...
