OSX Mountain Lion Server and DNS set up and migration - repost

I have a new server running on Mac OSX Mountain Lion Server. I want to set it up to run all of my web hosting and DNS management. I have a VPS Linux server reseller account run on WHM Cpalel. I would like to migrate all of the accounts on that hosting account onto my new Mac OS Mountain Lion Server. A DNS would need to be set up, accounts would need to be migrated and websites installed correctly. I would need name servers set up as well. I dont know how to do all of it, but I have some knowledge. I managed to set up one account through trial and error, but I dont know how to set up a DNS on this server to make all of the websites I have work correctly. Then after all this is done, I want someone to offer server support for me in case I need things done.
