Chiropractic email list USA and Canada

I am interested in obtaining a list of chiropractors in the United States and Canada. The list should contain each chiropractor's name and email address. If possible, having their address (street address,city, state and zip)and phone number would be helpful, although it is not essential if it would cut down on the size of the list or increase the price. I would like to have this in an excel spreadsheet.
