I have a list of 200 building addresses in the Melbourne CBD. Each of these buildings house multiple businesses. I need a Freelancer to go through each building and find out which businesses have their offices within it. I need a list that includes: business name, email, fax, phone and address. Please realise that each building in MY list will house MULTIPLE businesses. Willing to pay up to 20cents a business name in milestones of 50.
