specifically gave expectations of what data we were needing. email and phone numbers and sources from other places then linked in. In Skype discussion asked about that. Was told "no worries no worries we do this for Microsoft"
LinkedIn is a great tool, but we were looking for xray, booleen searching. He produced 6 names and charge me for 6 hours. That means took him one hour to find one name and just gave a linked in page. WASTE OF MY TIME and money.
