Website building and designing

My goal is to build a website to sell products and let people put their own products up for sale. I want it to be available for everyone and even big companies. I am looking to build a website that is easy to use and that will attract people. I want the website to be easy for anyone to use. So if someone wanted to start selling something they could very easily. I have a logo I made but I am sure it will be changed at some point. I have tried to write my website in code but I was pushed away from it and left with little to no time on learning how to code. I then pushed myself to use Wordpress but felt like I did not have enough time. I am searching for someone to help me build my ideas. I don't want the site to be just some smallEcommerce website I want it to be bigger.
