You should be able to just sign up for a Venus VPS here: https://heliohost.org/vps/subscription/?mem=2&cpu=2&hdd=50&os=ubuntu22
Since a VPS comes as a bare Linux install, you'll need to install a web server and related components then move your content over. Many users choose to install a free control panel to simplify things since a VPS is otherwise entirely command line driven. Hestia is one such free control panel that's widely used for this, though KeyHelp has also been mentioned on here.
I'll escalate this to Krydos since he supports VPSes. Once you purchase it and it's built, he can help you get it set up and configured if you're not familiar with setting up a linux box.
