I am a computer science university teacher from Tunisia.
Since you search for a freelancer not only to fulfill the job but to help you getting your way with this CMS, I should be one of the more appropriate ones.
I don't have a great experience with this CMS, for this I requested a relatively long time window, but this is not a problem because I have sufficient knowledge with other CMS like prestashop.
If interested do not hesitate to contact me.
