Good day,
I have read you all requirements and limitations.
Yes, you can add the content by yourself too. We will help you with that.
Are you done with the purchasing of the hosting?
I'm a senior developer with more than 9 years of experience. I have developed many websites which include websites of multinational companies.
I developed websites on WordPress, angular, PHP, Shopify, Open-cart, Ruby on Rails and Magneto using different variations like Payment method, product type, simple product virtual product, downloadable products and much more.
I can show you my portfolio if you're interested.
Message me so we can proceed further.
Many Thanks
AQ.
