Other than in exceptional cases when a publisher will take it on, the best thing to do is to self-publish it. This task can be undertaken for you by professionals, whose details are included in the Writers’ & Artists’ Yearbook.
These ‘self publishers’ or ‘vanity publishers’ will edit your book and have as many copies as you require run off, at a price of course. You can then distribute the copies as you wish.
Or you can try my publisher.
How can I be sure of getting my life-story published?
