Develop Marketing Contact List for sales of Property

I need an accurate data base of high net worth investors and buyers of property from around the globe, ranging from high end agencies and brokerages through to private Investment offices of families and corporations. This project will be split into 2 parts and I am interested in Bids for both phases. 1) Develop verified contact list to send emails that WILL reach its intended recipient in strategic geographical areas, in the main looking at: - UK investors, UK High end agencies and property dealers / brokerages - Mainland Europe, targeting Scandinavia and Eastern Europe (Russian contacts) - Middle East, Gulf connections with Private family and Sovereign offices - China, Korea, Taiwan, Singapore, Malaysia - Indian Subcontinent. 2) Once database is collated and verified I will need someone to then send contact email / internet marketing campaign out. I am open to ideas and suggestions so please make your proposals so we can start this project very soon. I look forward to receiving your bids
