do you really think it's that easy?
in most western european countries, you must have a staff who sell the ads/setcards in person this is still not a "online only business".... means local contacts.... knowledge of the local market... and and and BUT then don't forget most operaters of such sites have strong connections to club managers and much times they exchange shares and in some cases they don't like new players in the market.... in case you don't have really great balls stay away :D
