26 teams (13 boys, 13 girls) = $104,000 for uniforms alone (assuming $100 each, 20 home 20 away per age)
Income from 1200 @ $10 each = $12,000 x 10 home matches = $120,000
Assuming each coach takes two teams, 2 coaches per team x 13 @ $150 per hour (assume 1 x 2 hour training plus 2 hours on matchday = $15,600 per week x 26 weeks = $405,600
Sponsors would provide at most 10 cases water per week. Maybe do a deal on rest. Assuming average cost of water = $3 per bottle x 2080 (2 bottles each per training, 2 per match) = $6240 per week x 26 = $162,240
Assume bus for away matches @ $1,000 per team x 10 away matches = $260,000
Cost = $931,840
Income = $ 120,000
Defecit = $811,840
Each parent would need to contribute $1,504 per child.
None of this includes cost of bouncy castle, entertainment etc or spending money for kids to buy food and drinks.
KND2 I respect your concepts and thoughts, but it is impossible to sustain. Yes, you can cut some corners, but its not workable from a financial perspective. Running 3 youth teams and a reserve team (U23's) is a big drain on the small finances of clubs. But I agree completely that clubs have to involve children in the club, whether that be free match tickets for children attending with a parent or sponsors supplying free tickets for kids.
And the liming idea is good if it can be done in an affordable way.
