CRM data clean and web based research

Our CRM contacts need checking against public information available online and cleaning/correcting. Each contact has an establishment, contact names(s), email and a general contact such as website and telephone number. Initially this exercise is focused on UK contacts of which there are c.150 only, although if this is a success (I.e the contacts are good and correct) the work will be expanded to the EU and c.1,000 contacts. We need each contact checked and edited/amended using .xls that we will provide.
