It's impossible to start a business without start-up capital, you are right. But you need to invest not only in the creation of a website or its promotion. In almost any area, it will be difficult for you to do without modern, powerful and functional software. Many e-commerce owners choose to outsource software and application development services and try to hire only experienced professionals who have a good reputation for this field. For example, I recently found a company that provides bingo and poker white label solution. The examples of their work are really impressive.
