Extracting data from very large .csv files

Job ID: 32116976

Budget: £10 – £20 GBP

I have six very large (365mb - 414mb) .CSV files.

The files are details of all UK companies. In total there are 4 million records over the six files. I need a freelancer to extract the data for all companies that have one of four specific SIC code (business type) associated with them.

I need these full company records putting on a .xls document for me.

This is a very simple task but I do not have the time to do this due to the size of the files.
