You have to do your own homework, I'm afraid. Not because I'm reluctant to help you, but because I don't know your book like you do, and I have no idea of how you like to work and what your aspirations are.
I really think your best bet would be to spend some time contributing to our Query Letter Hell room, and learn how good queries are constructed; then when you've got your fifty posts, post your own query letter there for critique. If it didn't do the job with agents, it's probably not going to do the job for e-publishers either, unless you submit to the ones which don't care about the quality of the books they publish. And why would you want them to publish you?
