Get your problem solved with "zero mistakes".
i will use my expertise which exceeds 6 years to do your request.
In fact, i am a database developer originally, where I have great experience in creating, manipulating, administrating various types of database, i used to perform complex queries on Oracle, MySQL, 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.
So one of my best skill ever is "data entry" in English or Arabic.
Also i have a great previous experience in websites programming and testing, i think this will help very much.

Also you will get a coordinated results and hints, and may be you need me in other issue, because always i think out of the box.
So i wish i can work with you from NOW, really right now.
I am motivated and serious.
