Targetted list building

I need to invite people to attend a networking group and I wish to collate lists of professionals from certain professions in Sydney, Australia within 10 km of Chatswood (postcode 2067) to invite, namely names, business names, profession addresses, phone numbers and email addresses. My preliminary categories are buyer's agent, cleaner, architect, personal trainers, naturopaths, pilates instructors, yoga teachers, nutritionists and virtual assistants. I need 100 or so names (and other details) from each profession I have mentioned above. I have previously had someone bid on this and was presented with a list of businesses which were largely not related to the professions I am after. Please note that I am only interested in someone taking the project who is going to search only for the businesses I have specified and in the locations I have specified.
