Recommend Masters in Education Program in Massachusetts

I have BA in Fine Arts but after several years in the design field, I am seeking a significant career change. I am very interested in getting my Masters in Education so that I can teach elementary school (grades 1 though 6). I am currently subbing in the local school system. Can anyone recommend a good program in the Boston area that is not too expensive? I am looking for a 2-year program that is not more $25,000. I am also considering including “special needs” training into the curriculum. The schools that are in my area are Boston University, Boston College, Northeastern University, Emerson College, Wheelock College and Lesley College. It would be ideal if I do not have to travel too far outside the city since I am planning on working during the day and attend school in the evening.
