set up a secure vpn server (100-1000 devices)

It is necessary to set up a vpn server with high protection against blocking (there is a high activity of Internet providers for blocking vpn services) I had experience with such types of vpn as Open VPN, Shadowsocks and realized that I can’t handle it myself, since I can personally buy a server and set it up vpn according to a ready-made script, but I realized that this is not enough and I need a knowledgeable person in this area who can set up a server for me and I could not get confused in this headache by paying a certain amount and calmly use it even when blocked by the Internet provider (blocks happen daily). The number of devices depends on the quality of the product, if the server can resist blocking and shows itself worthy, then the number will be many, even very many, since the demand for this product is very high in my region. As you understand, I need a dude who will set up the server, and my clients will be happy))
