They're authenticating often unique or near-unique items (not the 7,000+ 1989 Griffey Jr they've examined), and often have to analyze and often research the stamping on back and identify the image.
I don't know anything about the pricing, but will testify that they do a good job at authentication/identification of photos. One is safe buying a PSA-ed photo.
