This is for non-fiction so not exactly creative- but thought you nice people might help out.
I'm thinking of setting up one-off workshops for non-fiction writers. (I'm an experienced mentor/ teacher, published author, and run an online course as well as mentoring clients privately, but haven't done a workshop yet.)
It would be for half a day and be a self-contained course that covered lots of topics.
I've seen other workshops running where the fee is anything from around £100+ to as little as £25.
If you were a serious potential author, what would you pay? It would be a small group, around 6-8 max.
