depends.....

i dont know anything about Bhop servers. Is it a mod or is it just pub style servers with special maps. If bhop is not a mod you should be able to use the create game function on CSS. If it is a mod you should start here https://developer.valvesoftware.com/wiki/SteamCMD

Edit: you should be able to "host" a locked server for yourself right off your computer on your internet connection.
