I am currently working in a freelance and consultancy basis. The sort of things that I do are:
Short term freelance contracts on a daily or weekly basis to work on specific client projects
Pitch hot-housing - either as the person cracking the brief, or cracking the whip with teams of people to get from a client pitch brief to a pitch presentation (or both!)
Creative Mentoring - with either individuals, creative teams or departments. I can work intensively over a short period in-house or on an ad-hoc basis over a longer period, whatever suits the situation best
Direct with clients/brands - I have a number of brands that I deal with directly and advise on a consultancy basis
