Agency/Part time work?

Hi all,

I am job hunting at the moment but am struggling with finding full time work. I have been looking at charity sector jobs as I would like to work in a capacity that helps people, but I am open to working in other sectors. I have been earning as a musician but would like to find some more stable work based in Edinburgh, but ideally keep a degree of flexibility so that I can still take gigs and not be chained to a desk 9-5 Monday to Friday. I thought that maybe agency/temp jobs might suit what I need, and wondered whether anyone has had experience with any? Ideally within the third sector or council. I have an undergraduate degree and past experience working an office job for a charity, as well as experience working in cafes.

Any help/insights/thoughts would be greatly appreciated!
