Custom Sculpture of A Horese

I am looking for a digital artist to create a 3d model of a client's horse. I should have plenty of photos to provide a good likeness of the horse. This will eventually be 3D printed on a 3DS system's 660 Pro at around 5" in size, so for the final deliverables, I will need to have a file with the colors included, such as .ply or .vrml in addition to the original zbrush (or whatever program you would like to use). Please anticipate 2 rounds of revisions based on client feedback. I will set up 3 payment milestones 60%/80%/100% to support that extra level of effort. I have enclosed a photo of previous animals that we have done to give you an idea of the level of detail that is needed. I need to have the first draft ready by 2/27/15.
