Get the CFI. If anything, it'll add new life into your aviation endeavors.

Local flight schools might pay $9/hour, BUT, you could go freelance and set your own rate. I'm pretty sure these flight schools are billing out CFIs at $50-80/hour and paying the $9. You can do better on your own as a freelance instructor. Find local flying clubs to get involved with. Spend time at the local airports and be seen. Meet people. Word of mouth will drive enough business your way.
