Someone fit and healthy who needs some extra money might consider advertising an evaporative (swamp) cooler preparation service in spring - new pads, clean/scrape out water reservoir, lube blower and check belt, check float level and water supply, etc. at a reasonable price in the areas where these are used, such as SW desert areas.
No special tools required.
No one here in far SW AZ advertises such a service. At 79, I'm not looking forward to doing it in a month or two.
