Hi Mannyman,
Browsing the AidPages will reveal links to many federal programs that are targeted at training support for low-income individuals. Just check out if such programs are available in Miami.
In the next section I have posted a link to a program that is targeted at helping Haitian immigrants, although being an American citizen might be an obstacle for you to participate in it. But also, why don't you have a look at it, you still might be eligible to get money for training?
