It wouldnt need a billionaire to get the football team up and running, Guernsey fc have a main financial backer but it is certainly not costing him millions per annum or anywere near it.
The positive factor about starting at such a low level is that the club can grow as the team progresses, it does not need a huge amount of money to get off the ground.
The current english model of foreign billionaire owners is not the only way either, Barcelona have 180,000 members who elect a president and a lot of clubs who have had to start from scratch ie Afc wimbledon, utd of manchester fc etc have adopted similar structures.
Regarding admission fees, it would cost as much to watch Crusaders at Seaview as it would to watch Borrusia Dortmund every week in the Bundesliga, no longer is the money at the gate the main source of revenue.
