Thank you
I think I've got most things up and running, I'll just have to wait for the DNS servers to catch up.
However, I'm not sure how to add a new domain, I assume I do this in Plesk? I've had a look, but there doesn't seem to be an obvious option to add a new one and in the "Permissions" section of Plesk, it says "Domain creation: No"? I've opened a support ticket on this issue, I'm just wondering if it could be cleared up here sooner.
