50+ and trying to re-invent myself

I have been in the software implementation/support side of things for 12+ years. I was making some pretty decent money and working remotely from my home office for a California company. My dilemma is that I have been downgraded to part-time. I live in Northern Colorado in a town that has few high paying gigs. I decided to leave the corporate rat race and go at it alone. With so many corporate takeovers and changes of the guard, in my career, I do not think I can stand anymore of it. So, what industry trends or business recommendations would you have for someone with my demographics? Just trying to get some ideas to chew on before I make the big plunge.
