Thank you.
It shouldn't be any direct costs to teachers. The lessons might need to be supervised by a teacher, which would be an hour of their time once a week.
As for volunteers, one hour once a week, plus travel, plus time to prepare (this will vary from person to person).
We need to raise £5000 pounds before we can register as a charity http://en.wikipedia.org/wiki/Charitable_organization#Charity...
