Hello newbaby90908,
Let me say I can speak directly to what you are thinking about. I just moved down here from Detroit in July 09. I have been out of work since. I left a lucrative job in Michigan (working for the man that owned the Pistons and recently passed away). I am in IT and moved here to be with family. Mobile is very, very different from Detroit concerning the business world.
Please make sure you have a job before you move here. I moved here on a promise of a new job from a friend of a friend (stupid move on my behalf) that evaporated as I was in transit. I have put in resumes all over town through Dice, Monster, InDeed and have had "0" callbacks.
Downtown Mobile is a nice place to visit and people do live there but to do any real shopping you need to travel to one of the suburbs or go across the bay. I am currently residing in west Mobile and have a wal-mart on every other corner. That is the way I would describe this town, it's a very wal-mart place to live. The newspaper is tiny compared to the Free-press and the job section is a joke.
Go to al.com and look in the Mobile section to see what the classifieds are like. However, if you're looking for blue-collar job then I am sure you will find something. There are lots of postings for pipe-fitters and the such.
I'm not trying to be down on Mobile but compared to metro-detroit area, it seems pretty backwards. Also, take into consideration you will be moving into the bible belt here.
I think the job market is tough all over, I have also been looking in Atlanta, Jacksonville and Tampa. Tampa seems to have a lot of jobs in my field but given the economy I believe the jobs are going to locals first and there are a lot of out-of-work IT'ers everywhere.
I'm not trying to sway your decision of moving to Mobile but I do not want you to make the same mistake I did. Make sure you have a job first. I am lucky in the sense that I am unmarried and have no children. If I was in that situation I would have played things differently, I was just desperate to get out of Michigan, now I feel like I am desperate to get out of Mobile
Also, I have other family in Daphne (Across the bay) and I tend to like that side of the bay more than I like the Mobile side.
Good luck to you.
