My advice is to go to a bike shop (not Wal-Mart, Costco, etc) and talk to them. I suspect most well-made bikes would do the trick, as they're pretty sturdy. I'd be more concerned with the way you feel on it, and the "extras" like shocks, and how the shift changers work, etc. Have fun! I never ride my mountain bike on mountains either, and not often off of pavement.
Just be sure to tell them that - be honest - because the off-road tires are often very knobby and won't do well on pavement or even smooth gravel. I changed mine for sort of "all terrain" which stop much better, aren't as skittery, etc.
