All the feedback to Equigraphic.com has been terrific. I was advised of just a couple little tweaks, but for the most part folks have commented that not only do they love the imagery, they love the sites look and function.
If you need web services, I highly suggest http://www.tinfoilhat.com
She worked with me to make the perfect site, balancing my strong sense of aesthetics and her knowledge of user experience and web trends to create a beautiful and functional site for a reasonable price. If you are thinking of a site creation or reworking, I suggest checking her out.
If anyone here has any more suggestions, please let me know. Of course if you know anyone who uses horse photography or might benefit from any of my services, please let me know. Marketing, your time is nigh.
