I'm usually a freelance journo/editor (of magazines, reports & the like) but have recently been asked to edit a book. I have to put together some costings and could do with some guidance on the best way to do this and, in particular, what the going rate is.
As I understand it you'd usually either:
a) charge a set fee for the whole project or,
b) charge an hourly rate
My feeling is that it'd be more sensible to go for an hourly rate (as I've no idea how long the whole project would be) but would be grateful for any thoughts from the pros
Thanks all
