Getting my single player/co-op game transfered to a server?

I was wondering if it was possible for me to rent a 10 person server, and get my single player game transfered to it? As in the character, buildings, and stuff transfered to this new server so my friend can play when im offline? Is this possible?

You might be able to copy the save file and move it to the server’s save file. cant confirm of this works at this time.

See thats what I thought and hoped, but im technologically impared and not sure how to do that, or even how to get a server.
