Convert 3 hour Semianr talk to mini book

We have recently held a 3 hour seminar and would like the content of the talk converted onto a mini book. We have audio recorded the talk and will supply you a transcription of the talk as well. Most of the book could be created by simply cleaning up the supplied transcript and making it read more like a professionally written book. We plan to see the mini book as an EBook on the internet. I picture the final product being professional. The talk we did was on how to progress from an artists (painter) to a professional artist, so a lot of the talk was based on marketing. Past experience in business and or marketing would be an advantage to you.
