Hey--we're in the same boat! Greed would normally prohibit me from offering help to a potential competitor, but....
MetzyMom basically said it all! I also got a couple of "How to..." books by professional fundraisers for some ideas, and I got a monthly subscription to the "Foundation Center" to find grants there. I found a whole world of untapped resources, both by doing straight and reverse searches. I did find some help among my parents too! When we sent out our volunteer survey, one of the choices in the "Ways I can Help" was "I have a contact for a Grant Writer." I threw it out there
just in case , and was I glad I did! One of the mom's has an aunt that is a (successful!) grant writer who is willing to help us out.
If you'd like more info on the Foundation Center, just let me know. We're still waiting for our 501(c)(3), so I've yet to see the payback, but I think it was worth the subscription just to see all the foundations that have the money for the asking, because most I never knew existed, and a lot I normally would never have even thought of applying to until I read the things they support.. Grant writing is a little daunting, because you have to work for the money, so when you get turned down it's hard not to take it personally. But the potential payout is alluring!
