How do you meet attractive grantors?

Like all grantwriters, I'm getting a little weary of the never ending search for new grantors. Old grantors are fine, but these days they're drying up faster that a rain puddle in the Mojave. So, where do we go for the new money? The search is painful and long. I try all the databases I know of to come up with 150 possible sources. I whittle those down to 36 by studying the guidelines and especially the web sites. I put everything I know about the grantee and his project together in a brief speech, and go to the phone. I deliver the speech to a program specialist. I ask if my project fits the grantor's interests today. If not, I go on to the next possible grantor. At the end of the process, I'm left with 20 possibilities. Of those, I have determined almost everything I can about the grantor. I have found out about the LOI, the proposal, the judging committee, the time, the money. In short, I have done everything I can think of to explore the universe of grantors, and then I write, proofread, and send, more and more often via an automated on-line application. What have I got to show for all this activity? Maybe a 3 in 10 success rate. Somedays it feels like 1 in 100 would be good work.
