There are a quite a number out there.
Acclaim Images - http://www.acclaimimages.com/
- are supposed to be quite good, 50/50 on photo sales. There not as fussy there compared to here regarding photo's being uploaded, just upload everything as a JPEG from a RAW file. You must have a RAW file for the image you upload to them.
I agree with Florian, stay clear of microsites, the only people that make money from that is the site itself. Doesn't justify your work to get paid a ridiculously small amount of money for a good photo.
See how it goes.
