The question is: what do u offer.
to be honest, ~3€/account is minimum. thats no joke and i dont want to insult u with this but:
u need ca. 3 hours/account to level. including time to create an email adress, an darkorbitaccount and of course the leveling. for 3€/account u have earnings of 1€/hour. and this is rly not that much.
of course you have to know if its worth then for you. these are my thought, what are yours?
