Customize my online store inventory (title, description, images)

I have just began a new online retail business whereby I will be selling the latest on trend clothing and potentially other products in the future e.g. cosmetics. Just to clarify where I am currently; - I have just started my trial with Shopify and I am using Ali Express via the drop shipping service I will be using Oberlo - I have purchased my domain name however I may also need assistance in the branding / design of the website - I need the categories/sub categories set up and also the various pages a typical online retail store needs - as an addition, if anyone can assist me on this but I have been trying to set up a business Gmail Workspace account to then link with a PayPal Business account however it says I need to verify my domain / update host settings for it I would prefer if someone was skilled in using Shopify Website creation so they are able to make it a fully functioning store for me however the main focus is to make sure all of the products are labelled nicely and descriptions are good similar to what you would view on sites like ASOS and Boohoo etc and if possible, they can look at sites like that to get an idea of the layout I would like in terms of home page, product page etc
