Health Services - Database Creation

I need to create a database of Doctors, Specialists and Allied Health Professionals for particular areas in Australia. This list will be used to send letters to the individual doctors to assist in recruiting. \r\n\r\nI have lists, (some hardcopy, some softcopy) that are incomplete. For example I will only have the doctors name. The role will require using my current lists and doing an internet search of the names on the lists identifying the correct doctor and obtaining further details including an address, phone number, email, website etc. \r\n\r\nSome of the existing lists will overlap particular geographical locations, so duplicate records will need to be identified and deleted. \r\n\r\nA master list on excel will need to be created so it can be used for a mail merge. \r\n\r\nFurther to this, I require that the doctors that I have more complete information on are still accurate. \r\n\r\nThe first job is approximately 30,000 doctors names. \r\n\r\nThe summary of the job is\r\n1. Review hard and soft copy lists\r\n2. Search names and addresses of Doctors to obtain where available address, phone, email, web etc\r\n3. Create database, removing duplicates and ensuring accuracy
