Hello, I have read your all requirements that you want a Shopify website and need to organize categories and sort products. As for Shopify, I have customized many themes and also have experience working with premium themes like Fashionopolism, Block shop, ShowTime, Retina, Brooklyn, Annabelle, and many more. I have also developed custom themes as well.
Go ahead and shoot me a quick message here so we can chat a bit more about the project. I’ll be at my computer for the rest of the day.
Regards,
