I know Joomla
Hi,
Thanks for sharing your requirement here at Freelancer, I will be more than happy to help you.
I understand that you have 9 joomla sites that you want to upgrade but can you please share the existing version because before upgrade to the new version we should check compatible version of installed component/plugin/module.
I would like mention that I will take payment only after completion of this job, I will first finish this job and then ask you to award and pay at the same time to maintain trust.
Regards,
Kapil
