Negotiating a fee with an SME
How much should one expect to pay for the services of an SME? I know this is quite an open-ended question but I would like to focus with particular reference to reusable course content and one-off bespoke courses.
If I ask an SME to write me a generic course that can be sold to many different companies, how much should one pay when compared to the writing of a course which can only be used by one company?
For generic, resaleable course content, my current thinking is to either pay nothing or a small upfront fee and then a commission/ royalty for every time the course is sold. Is this the done thing?
If I were to pay a one-off upfront fee with resale rights, I imagine the fee would be much higher but by how much?
What do SME's in the industry expect and how protective are they of their courses? I imagine a lot.
Any feedback would be appreciated.
