Build Email List of Target Demographic

Hello, I am looking to build a legitimate subscriber list *Opt In Only. The brand is targeting university educated social women aged 25-40 years old ONLY in Toronto, Canada. Currently the business had a professional contest page that automatically tracks and inputs geolocation of new e-mail subscribers into the backend and facebook setup that is able to effectively capture leads. The Launch of the product is at the end of August so the project will need to be done fairly quickly. If you have a strategy that is able to target this demographic in a timely manner please feel free to send me what you are able to do and please quote prices based on volume.
