Experienced Blog writer required for IT related topics

Hello.

I'm am currently looking for an experienced Blog article writer who has a background writing on techie subjects aimed at the average computer user to fully understand and act upon.

This job is for FIVE blog posts.

I can provide additional information and reference articles for each post but some additional research may be required by the writer.
