I think it is under egg donor recipients!
The agencies I have seen have a lot of blondes. It wasn't necessary to spend $50,000 to 100,000, they were simply on the list along with everyone else of all other hair colors and ethnic backgrounds. It seems surprising you are having trouble, but possibly it is different in different parts of the country.
There is a book on Amazon.com called "A Tiny Itsy Bit of Life: an Egg Donor Story" by Carmen Martinez Jover. It's a book to actually read to the child.
There are egg donor agencies that will search out a donor with specific qualifications (height, weight, athletic or artistic ability, ivy league education, etc) but they are very expensive--usually from $50,000-$100,000. I can't remember the name of the agency, though...if I remember, I'll post again.
Good luck!
