I need a interesting, exciting and pithy introductory letter to pitch to publishers

I have created a series of bi-lingual crosswords designed to assist vocabularly learning, please see my site crossmots dot com. These are now collated into a series of 8 books. I wish to hawk these books to potential publishers, but I don't do exciting, interesting and pithy. Please see the attached documents, the covers, the French book (cut-down version)and a marketing blurb background book. Please quote if you are interested in this work.
