Considering Enlistment to Reach Career Goals

I don't really know what questions to ask, but the delayed entry program for the Air Force maybe something I'm interested in. I say maybe, because I'm still deciding on whether joining the military is something I should pursue. I'm currently a junior in college. I can't afford to continue to attend school. So I'm looking to the air force as a way to attain my B.A. I know in my heart that I do not want to join the military. But as of now it looks like my best option. With military experience comes more job opportunities for someone my age. I've been working two jobs to pay for school. While dealing with the "EVIL" that is public transportation. Enlistment seems like the logical thing to do. I want to be able to travel, have my degree, and provide for my family (parents/siblings). I know this is probably to much information, but I really need someones opinion, story, and/or advice.

P.S. I've also looked into working for companies like Dyncorp, Fluor, or KBR..... I have yet to hear back. Opinions about these companies would be greatly appreciated.
