Get your problem solved quickly,
i will use my expertise which exceeds 6 years in databases programming.
In fact, i am a SQL developer originally, where I have great experience in creating, manipulating, administrating various types of databases, i used to perform complex queries on Oracle, MySQL and SQL server.
Also i can deal with data on an Excel file or CSV file or even a text file (with specified format),
then i can work out queries on those files as you need.

Note : May be i am a new freelancer on freelancer.com, but be sure that i am not a new database programmer :)
