Hi Raion,.
I'm OK with whatever or however you want to engage mate. I can spin up a FreeBSD VPS on our kit (PROXMOX) and you can install whatever you like. I don't interfere unless someone is doing bad things to/from your host.. We've got kit in four sites, some are smaller than others but they are all connected - we're a network business more than a compute one. But, if you let me know the compute and storage requirements I can do something. It won't be AWS pretty but it'll work

Imagine a shell host in the early 2000's, yeah, that's us. Bare bones. No Frills.
GDPR is a massive pain in the ares. The UK would operate under that policy unfortunately so it might still be a ball ache. Not sure really but we have a bunch of other clients who seem to be OK. Just smash a disclaimer on the site and Bob's your Auntie.
At a push (not sure what volumes of traffic of data you have) we could do something tasty in AWS though because we have the direct fiber connect into their cloud...I don' know what to say. Sounds like I'm advertising and I don't want to get booted out. Actually, funny story, I saw my thread had gone and thought it was moderated due to the possibility I was 'up to no good'. Was happy to see it was just moved.
Long story short - reach out to me when you like - I hope you can see my details or if not drop me a PM and I'll be in touch directly. Like I said, don't expect Elon Musks crack automation team to deal with this. But all the same my heart will be in it.
