Compile 900 letters using supplied database with additional data mining required

I have compiled a database of approximately 900 residential properties that have sold in Sydney in the last 12 months. Using resources including RP Data (username/password supplied), [login to view URL], I need you to discover owner details, drop them into an existing MS Word letter template, print (laser printer) and insert into an envelope with same owner details affixed. I\'ll supply database, RP Data username/password, paper and envelopes - you supply initiative and the hard work.
