E-Mail Marketing List Generation

Hi, I would like to get a list of Occupational Therapists in Sydney, Australia (within a 300km radius of Sydney). I am looking for primarily their email addresses but if possible would also get their names and organisations also. The email address could be for an individual Occupational Therapist or for a clinic or organisation which employees Occupational Therapists. There should be more than 1000 occupational therapists in Sydney... perhaps even 3000. You might use Google Search, or other methods to find out the information.
