I have a relative in LC that gets VERY GOOD tech person for $40 / hr and pays ONLY for time in the home, no transport. Most calls under 2 hrs, longest wait was 2 days for a 'non-urgent' need.
But that is only Windows and Mac support, not sure what a 'real' tech person gets that can offer something with performance and less ICONS and dogs with wagging tales...
You might need to re-calibrate your expectations, or work 2.5 jobs (that's what I did for 15 yrs) My wife enjoyed all the free time and extra $$ to spend
, plus we didn't fight much
I'd figure out some medical offering for the hospitals that have to care for so many 'walk-in' / illegals. I will bet you could get a Gov / Insurance grant to do some tracking / projections / reporting. You might be able to include other border areas and get a mega business with mega $$ flowing. There is also a large senior population, so health care and simplifying filing and choosing health plans might fly. Just be careful in your career choices and stay technical, as laborers flow in every day to work for cash. They continually knock on your door and TELL you you need something done around the house. They are very persistent (won't leave) and if you hire / pay them, they will be back frequently with their friends / family.
