My book is almost done

So my book is almost done. I need to get an ISBN number and then self-publish, till I can find a big publishing house that wants to snap it all up! I hope this will be a hot seller and that I can go to different groups - churches, moms clubs, MOPS etc to lecture about it. If you have a group that needs a speaker, let me know! I live in the metro Phoenix area and would love to come talk for about an hour on what I do and give some demonstrations!
