Hi Sarljo, I'm sure there would be a pretty wide range depending on who the employer is. I noticed that Guilford County schools have openings for custodians with a starting salary of just over $2,000 per month.

The salary for jobs working with adults with disabilities would vary pretty considerably depending on exactly what your job role is but there are definitely those jobs out there. This list might be a start to show you what agencies are in the area and see if these agencies have any openings:

Salaries for the Triad may be a little lower than the Triangle/Raleigh area but the cost of housing is noticeably higher in Raleigh and the Triangle (with steeper price increases) than in the Triad. I'm sure there could be exceptions but for most jobs in fields you've mentioned, you'd be better off in the Triad because of the Triangle's housing costs.
