Introducing Non-Trivial Quest educational board game

I am a developer and manufacturer of a new educational board game called "Non-Trivial Quest." I am new to this business and need help and advice in many areas including exposure and sales. Who in the board game media should I send a sample of my game to for evaluation and rating. Who are the best reps and distributors that I should contact. I will be an exhibitor in March at the GAMA trade show in Las Vegas and the WTHRA trade show on Long Beach and our Web site will be up soon at www.Non-TrivialQuest.com.
