Sir, i already understand what you need, i am developer, but i think my developer skill won't used on this project, i just need to manage your shopify template and adjusting it with your reference, right ? just want to be clear, there is no coding in this project ?
I ready to do this jobs, manage and adjusting template that comfortable to reference site, make it look good and friendly by user, input product and categorize it, and other thing in your list
I have use shopify two times for my local client, they like it how i build store, however, they site already gone, because hosting and domain already dead :v
as long i got direction from you, i will work in your command, you like one section, keep going to other section, if don't, revision it until you like :)
Lets continue to little / small chat, i will take my coffee to see what your response :D ...
Thanks
