Helping my dad get a job?

My father was let go from his roofing job about a month ago (he's since spent his time doing side jobs for other people).

The problem is finding jobs he's qualified for that pay more than $20 an hour, which is what he was used to being paid and he currently needs to be paid at least that much to pay the mortgage.

Unfortunately, most labor jobs pay $10 an hour and if Dad takes one, he and my mom would have to declare bankruptcy to keep their home (Mom also has a job).

Should my dad take a lower paying job and hope that it starts out at $10? Right now, he's "freelancing" his services but would appreciate another job.

Dad has been thinking about taking a job working with solar companies but is disappointed that they can't teach him the skills on the job.
