We are looking for contacts of companies around the world, which could be relevant for our business. We want to begin with contacts of architectural firms in Singapore. Companies from this list: [login to view URL] We want contacts of all the members of these companies. In each contact we need the following catagories: Company name, contact name (if it is not personal please specify: procurement department, info, etc.), and the email address. You could find the names of members of these companies in their websites, Linkedin, etc., and then you could find out their email addresses (it usually folow the same pattern). We will pay 0,03 $/per contact. If you find any other ranking of architects, which could be interested for us, we will also pay for the contacts (but send it to us before to evaluate it). We will need much more contacts of companies, but we will begin with this target. We need to finish it as soon as possible. Thanks!
