I had little experience in starting my project. I can say that first of all you need to find a good programmer who could develop a website for you and all the processes in it. In my case, it was an acquaintance of mine and I had an agreement with him on the distribution of profits from the project 50% to 50%. In general, this is one of the important considerations. The problem of finding promotion professionals comes to the background. In my case, I relied on a prepared audience that was already ready to participate, for you you need to find, for example, promotion managers and order a service from them to promote your project. Again, to be successful you need someone who can create ad content. Typically, this is also the job of promotion managers. If you find professionals, the chances of your project being successful are high. Wish you luck!
