Foot in the door

I have an idea that I think would make a good graphic novel, but I don’t know any artists or publishers (or friends, neighbors or relations of any, for that matter). I plan to attend the Boston Comic Con in April (http://www.bostoncomiccon.com ), and to take a day off from work to ask around where artists hang out in Boston. But I would appreciate anyone throwing their two cents my way. Thanks, Patrick
