Of course it depends, but here are some figures for you, and an explanation of ranges of charges.
The pricing of outside seminars set by third parties are out of my control, as they include their own costs as well as financial support. They range from £200 to £350 a day per person and may well be subsidised as part of their own bursary scheme. Day long seminars arranged by myself cost £350 a day per person, including VAT. Currently our focus is on a full length, 12-week Master Course, which is in development. Please do get in touch for more information.
