We cannot tell you what server host to use due to rules of the site. (This)
But if you want to host it yourself, try home hosting. Download the Multicraft panel, install it, and port forwards your DNS. Lots of tutorials on how to do this on Youtube.
Yes you can do what they do. But yes it does cost money and lots of time and effort put into it. But are you asking how to open and run a hosting service? Or how to host a server yourself for yourself?
