hosting a server is not for free.
if you want someone to host your server, it should be something good, which didn't exist before.
(for example a new kind of subgame that is different from the other games, by using a custom mapgen and many other stuff)
for creative servers, there already exist quite a few, all with unified inventory, or it's light version for better performance.
they also contain most, if not all mods that add clasic, medieval and/or modern elements to the game.
if your server is not completely different from those, the chances of getting it hosted by someone are very small ...
(you could also apply to become a moderator on a creative server, it would give you a similar position. if that is what you are looking for.)
good luck ;)
