For face-to-face work I use rooms in Cambridge. I also work online with people where meeting in person would not be practical.
Some people come twice a week, and some less often than that. In general, the added intensity of meeting twice-weekly enables significantly more to be achieved than meeting once a week, and it’s rarely effective to meet less often than that.
I operate a sliding scale for fees, according to what people can afford.
I do charge for missed sessions, or sessions cancelled at less than 24 hours notice (unless it is possible to find another time to meet).
