It's probably okay to do for 1 month if you don't want to host the server on your own PC. I personally had a server hosted on my own PC for a couple months and it was hard on my PC, had some server problems, but it was still very much successful for the first month or two. No idea who to recommend but i'm sure any popular service will do. Get used to knowing where the files and data is for your world so that you may host it on your own PC in the future.
