Hmmm....
As a start, maybe.
I'm a pretty big believer of "not your hardware, not your data." it would be a really hard sell to try to get my to change that now.
For someone else, you'd probably need to:
-explain why you'd want to host your own relay
-show a clear path as to how to move said relay
-offer to help them move the relay to their own hardware when they are ready, possibly even selling a hardware package optimized for this task.
However, you'd have to compete with things like umbrel that are doing just that and much more. (This is the path I'm going down via a proxmox server.)
