Build a customer database

We are a new online women's clothing company based in Australia and would like to develop a database/following of approximately 200,000 women from 35 years old + over the next 12 months. We have an extremely unique point of difference. Ideally our customer base will spread over Australia, New Zealand and the US. These need to be legitimate customers not just blank email addresses. We have set targets and if you achieve them we will be happy to pay for your efforts. Please get back to me with a brief proposal and costing over the next 12 months.
