By now you should know what it takes to become a Keynote speaker. Not everyone looks to Keynote Speaking as a means of speaking but it is one of the most lucrative speaking engagement gigs you can possibly do.
It will obviously be necessary for you to work your way up to this level of speaking. I started with service organizations such as Rotary, Lions Clubs, Kiwanis and Soroptomist. I also spoke at organizations such as Professional Women in Sales, National Assocation for Professional Sales, New Age Bookstores, franchise meetings, expos, Chamber of Commerces, Teleseminars and Webinars.
Associations are the best resource for monthly presentations which can turn into quarterly regional meetings and then annual conferences. The Trade Show National Network is a wealth of potential speaking engagements.
The best keynote engagements are ones designed by a group of people who have the same target client base. Either they organize an event together or hire an event planner to bring qualified potential clients to the event.
