Career change after a layoff, where to begin? after 12 years as a janitorial supervisor

After 12 years as a janitorial supervisor I am thinking about moving into a different field. Any experience at all would help. I have good customer skills and I am comfortable with spreadsheets. Has anyone made a similar move?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

You likely have more transferable skills than you think. Write down what you did, not what the job title said.
