Could you use your middle name as your first name for a while when cold calling? Now you become "Alan Powell" or "Josh Alan Powell" or something like that for a while until people forget, which they will eventually. Maybe if your middle name is catchy you could go by initials....for example, I have a friend who's first name starts with a P, middle name starts with a J, he goes by PJ. Could you become "JP Powell" for instance? I think there are many ways you could rearrange how you refer to yourself....
