If you want to make a server its easy, there are several good minecraft hosters out there who would help (eg. MCprohosting (USA), Veoserv (UK)) I have used both and have had very successful servers with them with little to no lag. Also youtube is your best friend if you want to set something up like a server you will find countless videos on how to set up plugins or a server itself. Also having a paypal at 12 is against the law (Unless its a student one which you have to be 13+ and live in the USA) I hope i helped and good luck!
