Some chimney sweeps inspect wood stoves and attics. Carbon Monoxide testing is often required. There is little competition.
If this is of interest, read the Chimney Safety Institute of America’s website. The Chicago Tribune had an article “Chimney Sweep Keeps Home Fires Burning Safely” December, 2010.
You can google the Chimney Sweep companies in your area and ask whether they need help. You can ask friends, neighbors and acquaintances whether or not they clean their chimneys regularly.
I once knew someone who advised me to constantly “Keep spinning”. If things are not working out, keep your mind active, keep thinking of unusual solutions to problems.
