Happy New Year Raymond. If it is an academic book, there is a set course for that and publishers that specialize in this type of writing. I would talk to the other published authors at the college and see how your book compares and how they proceeded. If the book is geared more toward the public, you have many choices, such as self-publishing or submitting to a publisher. To me a lot of what you are trying to do with the book would determine the course. If I wanted to be a speaker and use the book for credibility, self-publishing works well and you drive your own sales through speaking, email lists, blogging and other social media avenues. You also might talk to a local writing agent and get an opinion on what you have created and the path forward. Hope this helps.
