I agree with Auburn- AMF is a good place to work, and a good place to build skills and time relatively quickly. Depending on your base, you could expect about 2 to 5 block hours/day, and the Beech is a good plane. However, getting hired directly as a 99 CP would likely depend on your experience.
Ziggy is also right- the schedule starts early and ends late. Expect to be away from home about 14-16 hours a day, minimum.
Some runs have a Sat morning flight, as well. Finances are an important part of the equation, as well. Several websites can give you a decent idea of what the pay is like, but a second income would probably be a must for a family.
Also, where are you located? If you have to move, that will make a tremendous difference in whether it's a worthwhile move. Commuting is really, really tough on you and the family, and strongly discouraged by the company. I've known a couple commuter pilots, and it was a big strain. If you're near one of the bases, see if you can talk to the Asst. Chief Pilot, and find out if you can get a basing guarantee and the likelihood of getting hired into the 99.
