What job would suit me best?

[GwennyWen]

I worked for 20 years in our family business that doesn't have transferable skills (painting restoration). The business closed after the death of our parents and I have been working from home selling my art work for the past few yrs. It doesn't bring in enough to sustain me beyond the next two yrs.

I am now 50 and single to boot, and facing a brand new start.
Can anyone think of a job that might suit my requirements?
I am an introvert so would prefer not to work in a big corp or in any kind of zany 'team'.
Would prefer to wfh ultimately but am flexible.
Non manual.
Above minimum wage, if only a small amount.
Would like to be able to learn skills on an inexpensive shortish course (can't afford another degree)

I am good with tech, used to like the idea of counselling but never got into it. I am fast, bright and friendly, but would really prefer to work in a small space or alone. My previous experience involves arts so quite out of the loop!

I don't want an enormous fast paced restart. Something modest will do. It would preferably be something that can get my brain rolling, so cleaning or bar work not my cup of tea.

Arts / Museum admin roles might suit. There are a fair number of behind the scenes roles at the bigger institutions (I have friends who worked in marketing & cataloging and imaging of collections).

Thank you everyone for your advice and ideas.
I have been thinking about using my existing knowledge perhaps, including gallery work, or getting involved in community projects teaching creative subjects such as collage, digital art, etc. Nothing skilled exactly but stuff I may be able to make money from and progress from there.
I have always kept myself to myself so much that this will be a challenge for me!
I would, most of all, love to run my own business, selling my work as I already do but with another focus too.

Of course if my back was against the wall I would take anything, which goes without saying. After researching admin and related roles I do think this would be too stressful for me, even though I am aware that many people love it.

I live in a small market town of less than 3000 with one large supermarket, so will have to give this some thought!

Could you teach art OP? Either at art college/uni/local community course or in your own home or a hall?
