Hey Byron, these metrics are about the same as my bread and butter properties. Since you guys don't have too much experience, I would spend more time on finding the right contractors.
The math is pretty simple but your challenge will be dealing with contractors and ensuring they do quality work at a competitive price. I'm sure you can find contractors to bid on your project without having to pay them for a quote.
I would spend time interviewing a few and listening very intently when doing the walk through. My guess is that each contractor will address some different items. You should put together a scope of work and make sure each contractor are bidding the same items as well.
@jscott has a great blog at 123flip.com which will answer virtually all of your questions on how to correctly run a flip. Of course you can find everything you need on BP as well.
Hopefully this helps and best of luck. Good to hear you're jumping right in and taking action!
