From my files: Nathalie Scott of Gotham Literary currently charges $55 per submission, which includes a half-hour representation fee. She sends out 5 submissions per month. She also offers editing for a flat fee of $5,000 (it's a conflict of interest for an agent to double as a paid editor).
She has been around since at least 2002 (previously she was with the Caroline Hutton Agency, which also charges fees), but to my knowledge she has no track record of commercial book sales.
Crisci books are out now, by "Orca Publishing Company" of Carlsbad, which ... all evidence suggests he owns. (Not to be confused with Orca Publishing Company of Oregon.)
As for Ms. Gray, considering that 1) there are a few Gothams out there (bizare example) and 2) her books are with imprints of Houghton Mifflin and S&S, I dare say her agent isn't with the Gotham under discussion here.
