Hi Charlie,
I do a lot of contract work, but didn't respond to your preview post. The real reason for me was that I office out of my home. It looks like you're looking for someone to come down and work in your South Jordan office every day. I'm sure it's not everyone's reason for not responding, but, for me, changing my work habits like this didn't appeal.
I imagine many, if not most, software contractors probably feel the same way. Coming into an office isn't an unreasonable requirement, but you might consider asking people to come in a couple days a week, instead of every day. I keep pretty regular hours, but I know many who work 2-3 hours here, and 2-3 hours there and feel they really excel in that type of environment—ya know, the freelance dream, right?
Hope this helps. Good luck
Cheers,
Trey
