I don't want to be a douche, but you shouldn't share information about hosting, what you should share is true words if the game laggs or not (I mean, do you lagg when playing local host? if not... it's lagg free, but then your internet is another things)
And Harddrive isn't something you need much of... 1Tb, 2Tb, wtf? You need max 5 Gb to make the server stable, and a good rpm.... but having a hard drive at over 500 Gb is just waste of money on something that you don't get any use off.
If I were you I'd take those money and put that in processors or ram, or maybe something to speed up the net.
Last, It looks like a pretty nice project, I hope you succeed with custom map and stuffs =)
People who take time to make a own map not based on real tibia deserve to succeed =)
Cheers
