You can get dedicated professional hosts like redstone hosts and such. You may want to search the Internet for the prices and such. Some offer really bad hosting but some give you the most out of your buck. First you might want to host your server on your computer(just my idea)and wait for popularity and ask for donations then get hosting there are lots of tutorials online on how to set up a server. If you have any questions just ask me.
