I'm seriously considering going back to school to get some training that will make me get a better job.?

I went and checked out Everest College in Illinois, they were very nice and even got through most of the financial aid that day. I have been looking online and seen some negative reviews on them. I would go back to city/community college but how will federal Student aid do me since it's been over 10 years and I was on academic probation as I was in a bad wreck and had to drop everything. My GPA is alright. Will I still have to pay for 6 credit hours to release or can I get new FA and get the full grants since it has been so long?? I want a degree that is gonna get me a good job and not pay a tech school to steal from me and I be the one paying for years to come for nothing; I'm aware that to get anywhere you have to work at it and I do. I don't sit and wait for someone to do it for me like so many nowadays. If you know how it works with FA pell grant please answer if you can as I know ultimately it's them that says yes or no but would like others input on this so I know where I may stand now. Thanks.
