Sales representative for publishing course

I run a specialised course for Picture Researchers/Editors/Photobuyers. I am based in London but can travel anywhere in UK, although most relevant companies are in London.

It is highly acclaimed and well received by specialised audiences.

I only run it in-house at publishing companies, picture agencies and other organisations which need my specialist knowledge and training.

I need a sales person to directly call relevant publishers and close the deal for me to come and do my one-day course.

I will provide a copy of Writers and Artists Yearbook and my brochure as sales material, plus feedback from previous courses.
This is a premium course and attracts a premium fee, so I would expect to negotiate a fair return to the sales agent for successfully closing sales to companies, organisations and institutions.
