bakery business needs setting up stores as per area

We have recently installed Lafka theme on wordpress for setting up our bakery business. Now, we need someone who can do setting to show our closest branch in that particular radius, when a customers enters a delivery location. We need video recording of settings/solution. What problems we are facing, and where we need the help. 1) Setting up of branches as per area name or zip code. 2) Setting up branch managers. 3) Logo size and location from where we can set logo, and footer area. 4) Newsletter sign up for customers. 5) Product pictures sizes, Category Picture Sizes, Background Sizes, Banner sizes. 6) Fixing of Global store settings, and individual store timings or setting. 7) Setting up new products and categories. More over we need a person, who can do required changes with a video recording. So that it will help us to do the changes or setting up things for future. Regards, Ishdeep
