That is a big dream and not realistic in building a sustainable club with that timeline.My idea for new clubs
Primary Schools be designated to the existing club and the new club. Players must play for their designated club
A GDA be appointed to work full time with the new club and their designated schools
Year 1 - set up go games teams for 7-12 year olds
Year 5 - have a fully functional underage set up for 13-18 year olds
Year 10 - have a fully functioning adult section and club in general
Dream big and deliver
Year 1: U6s and promoting in the Junior infants in the designated schools. Focus on getting a solid start. If you try to field teams from U7 to U12 in year 1, it is destined to fail as they won't be able to recruit enough players and it gets off to a negative start immediately. If you can sustain one group at U6 for a year, the motivation will be high to push on the following year
Year 2: U7 & U6.
Keep going up 1 year each time with that first group that started.
All they would need for the first 7 years is a green field with basic toilets and training facilities. Wouldn't even need a full size pitch.
For year 8, when they are playing U14, they would then need to be getting access to a full size pitch, but after 8 years and hopefully 8 good groups of parents, fundraising/goodwill would be achievable.
Slow and steady.
