Fixing issues in a WordPress site

I have some fixing issues of plugin and design in [login to view URL] . The tasks are: 1- customize the urls of the stores: [login to view URL] of the town or city of the store/name of the store/name of the product if a product is shown. 2- When a search is made by a product, brand or category when the products are displayed, it is done inside the store where the search is made, not on a page outside the store. 3- customize the stores in a format . 4- On the store search page, we now have a product (which should also be from brands and put it in the text above the bar), store name, and the other search must be by postal code or name of town or city, as we had on the page that had to be removed because it did not work. 5- SEO of the stores when add them from the administrator panel, and 6. How we can change that.e professional Digital Marketer to create the branding of a market place portal.
