First off, there are wayyy too many faction servers. I doubt any hosts would be willing to do this. Your idea isn't really"unique", you're just changing the theme. If you can't even afford 0.75c a month from www.wulfhosting.com for 512mb or 1GB for 1.50 per month then don't even start one. I can tell you are under 12. Best start is to wait until you get a job or ask your parents.
