Market Research To Update Database

I have a database containing ~ 2500 companies. The companies vary in size from small to large - and located in various countries (e.g. China, USA, Europe, India...). My list contains the company name and most (95%) have a website URL. I wish to identify ONE KEY CONTACT at each company. If the company is a multi-national organisation, the contact should be from the Headquarters (HQ) - for example, Siemens is a global organisation - the HQ is in Germany - so the key contact should be selected from the HQ in Germany. The KEY CONTACT can be either: - Chairman - President - Chief Executive Officer (CEO) - Managing Director I wish to obtain for each KEY CONTACT : - Title (e.g. Dr. / Mr. / Mrs.) - First name (e.g. John) - Last name (e.g. Smith) - Role title (e.g. President) - Company email address (e.g. [login to view URL]@[login to view URL]) - Company address (full address including postcode / zip code) - Company main activity - Company size: - Small company < 100 employees (< $10M sales revenue) - Medium size company 100 - 1000 employees ($10M - $500M sales revenue) - Large company > 1000 employees (>$500M) The work needs to be completed accurately - it will require a skilled market researcher (not a computer) to read each website and identify the correct contact and identify accurately the main activity of the business. The project needs completing by mid-September.
