for our regular meetings we meet at a church, but we have been able to use a training room at a bank for our workdays and special teachers - lots of tables, outlets, etc. and since we're a non-profit it's no charge to us. Check with businesses and company's in your area and stress that since you're doing charitable work they MAY be able to get some credit (tax and otherwise) for helping in this way. Many companies have training areas that go unused a lot.
