build a website prototype

i am trying to build a website for local creators in my area to sign up and sell their products. Something like shopify. This website will allow sellers to sign up and create a store' which they can display their products and other relevant product information (eg price, description, product images etc). Buyers can search the website for products just like they would on amazon/alibaba or they can just browse each store to see what each seller is selling. This is just a rough description of the idea as i envision it. I am open to alternative suggestions of how the website should work For now I need help building a web prototype that i can host locally and display to potential investors. It doesn't have to be a complete website. Just something to display the concept. I need the prototype to have four pages: 1. The landing page (which should be simple and beautiful! Not boring though) 2. 'Browse Stores' page (with dummy stores displayed in a classy fashionable way) 3. A dummy store page (with seller's brand name and products) 4. a login page (which gives options for whether the user is a buyer or a seller) 5. A 'Register your store' page for new sellers I haven't decided on any colours for the website so feel free to use whatever. As long as they go with the theme and purpose of the website
