Do you think you would have much call for mobile motorcycle tyre fitters in wiltshire/gloucestershire?

It's looking like I need a secdond income, like many others in the country at the moment. A second income from my own business would be better.
I was thinking about purchasing a catering trailer but having no perm pitch that I could make a good return on it has to be selved sadly.

Web disign is very slow at the moment and I end up doing it for ntohing for people starting out to help them get going so not really worth anything.

Mobile tyre fitting with out of hours call outs etc. thoguht it might be a good idea. Not sure if it would be cost effective
