Hi there Native English speaking Joomla experts here.
We can write a perfect Joomla Admin training guide for you in pdf form with screenshots from the admin side to demonstrate the text. If you can supply a list of topics to cover we can get onto this right away for you. Check out our reviews here and you will see that not only are we Joomla experts but also communications experts. Its a no brainer we are the people you are looking for this project! The project will be handled by a Native speaker from London so it wont be full of the usual mistakes that you get from outsourcing to India or the Philipines.
