I need a list of 5000 dentistry Clinics in USA, preferably from East Coast States. I require the following details to be collected in a spreadsheet: Company Name Contact Name (if exists) Contact Position (if Exists) Company Phone Company Phone (Alternative) Company Fax Company Address (separate fields for address, city, state/province, country) Company Email If someones already has a list with what I need that will be great. I'm waiting for your questions. Happy biding.
