I am looking for a writer who can write a good easy to understand manual for a small software application.

The writer needs the following:

-Clear perfect written english
-Access to Active Directory
-Editing and creation rights to active directory users and contact
-General understanding of Active Directory, Creation of users, Organisation Units and general AD Domain knowledge.

I need the writer to write an manual in clear english to end users who might not know much or anything about Active Directory structure. The guide therefore need to be written in layman terms.

There is a short guide to how the application is working, but is more like an internal paper and not usable for clients and non tech staff.
