Hello,
My name is Elvira, full time freelancer since 2012.
I would like to help you with this project. I have done many similar projects before, adding products into various platforms. I did not use Square Space before, but I already found their support page, watched their videos regarding uploading products, adding variants, etc. It is very intuitive, I mean, I already did these steps on Prestashop, Opencart, etc. They are very familiar to me.
Available to start right now.
I look forward to hearing from you,
Elvira
