You may have such a happy 12 year old boy there that he may invite some of his friends!!!! You sound like a person who really cares and one who got into the profession for all the right reasons.

I don't know where you live but I am hooked on the 'Craigs list'. It is a free classified add on the internet. They have mnay sections, one of them is a free section. You can also post on the wanted section but from my experience reading those it's not a section that get a whole lot of traffic. Anyway, post some of your requests in the free section and see what people might have for you so you can augment your budget. There are also grants that you can apply for supplies.
