I can host your world on vanilla if need be but it will be £12 for 6 months but the server s up nearlly 24/7 and your world will be whitelisted. The ranks could be a problem though cause of the way this would work but i can certainly host your world if you need it hosting for the price stated above.
EDIT: This will be a world hosted on my server called Forgotten Islands with 1GB ram and 24 slots.
