I want to create my own website that is an online store, how can I do it?

Does anyone here by any chance have their own e-commerce? Because it is quite possible that only people who have their own electronic commerce understand this question. Seeing that more than one person who created their own online store managed to earn a lot of money and get great profitability, I have proposed the great idea of ​​creating my own store in line, but I want my online store to be on a complete web page, something similar for example to Amazon or Aliexpress, but I have no idea where to find a developer who can create this website and online store for me, does anyone know what developer can do? ? recommend me the best developers of this type
