Yes, you can add content to your site. 

I have been using the Joomla CMS (Content Management System) since 2009 to create websites.

In order to keep your website looking professional with consistent styling and formatting, you will probably need some training which I offer at my normal hourly rate. 

Alternatively you can provide me with your content in a text format and for a monthly fee, I can upload it to your website for you. You will also need to provide high quality images as jpegs or png files which I will scale to suit your content.
