Rent two Ubuntu servers on theonionhost.com (They accept crypto and ignore DMCA complaints), use one server as the destination server, use the other one as a proxy server. Install Nginx on both servers. On the proxy server use an Nginx reverse proxy to the destination server. On the destination server, install ufw (firewall) and block all incoming requests except from the proxy server IP (This will hide your destination server IP address from whois tools and DNS dumps as well as companies that gather information from IP addresses)
