Its just my 2cents of advice that , be careful while sharing the content with your clients/vendors. At times they will not approve the content and may tell you that they are not satisfied with it but the fact would remain that they will use the same for their training which will be done by their in-house trainers. I have seen this happening.
I work as a corporate trainer and have created enough content. Coming to the price, it would depend on the availability of the documentation(Is it easily available/sourced), no: hrs taken to create it, quality and its impact on the audience.
Guess this should help you in drawing a conclusion on the price part of it as you would be the best person to judge your capabilities on creating a document(Know thyself).

Sound advice from the other members. Pricing should be such that you are in a win- win situation. Do bear in mind that your building a long term relationship by offering a fair price. Coming down to basics, you could calculate the time and effort put in and come to a fair cost. Doing a little bit of "RnD" and Marketing strategy is also good. Its always good to know what the market trends are to be competitive in today's market.
All d Best.
