Not really possible.
Setting up and running a private server is very simple but if you put in no work then your server will not have ANY reason for people to play yours versus any of the other hundreds of servers out there.
If you are not willing and able to spend the next few months working your ass off to make your server unique and the few months after that paying for premium hosting and advertising the server then I wouldn't expect anyone to play the server for more than a day or two.
