Another option to look for is a workforce development group. I worked for one for three years in Richmond, VA and they are in most decent sized cities. They are a government funded organization that help people get their GED and job training skills, including the fees for technical training at no cost to the individual. It seems like you already have an idea about the type of work you want to do, and many of the trade jobs are what these groups are geared towards. In the three years I worked there, our organization helped hundreds of people a year with school tuition for trade schools and/or certification programs (nurses aide, etc.) as well as resume assistance, job skills coaching, counseling, etc. You do have to qualify for the program, but if you are unemployed and don’t have marketable job skills, you would be a good candidate.
