Configuring a store based on shopgold

Hello, I am looking for a company with a completion date of the end of September to create a store based on shopgold on the model of the already existing one at another address (also my property).

The store is already installed on the server.

I need:

- configure the store under SEO, etc., payments, terms and conditions, shipping, etc.

- creation of a menu

- creation of sub-pages for the store

- possible editing of the template or creating a new one

As a summary, following the existing template, the new one is to differ in terms of SEO and is to remain for me to introduce products.

The store must work well on mobile devices

Products will be transferred from the existing store so it will be important to maintain the menu structure.

Please send me offers and price range.
