241870 Joomla and WordPress updates

I need someone to start today! I own a network of new websites which regularly need to be updated. Several websites are Wordpress themes which often require updates to the theme, header, navigation links etc.. Another site is Joomla and this needs updates, plugins installed, etc. I am looking for someone who is affordable as these sites are very new and not highly profitable, but this will result in steady work. Please let me know your experience in Wordpress and Joomla. This could result in long term work relations, and I have work to assign starting today. With regards to price, please give me an idea of what you would charge for each hour of work.
