My 2 cents.
Don't even consider the "Aviation College" gig. Find a good reputable Flying School, close to where you live. More importantly, find a good Instructor.
Keep working as an AME, fly like crazy in your spare time, take vacation time and go hard with the Flight Training.
Private, Commercial, Multi IFR.
Once you find a good first job, then resign your AME job.
The sky's the limit, Air Canada is hiring guys in their late 40's. IF (?) that turns your crank, consider it. If not, there are going to be so many jobs around, you'll have your pick.
Your age, your Aviation background, will be invaluable.
Best wishes.
