"We want you to focus more on shooting. Simply upload the unedited images after each shoot, and we will take care of the editing process."
Also, lol : "It is necessary to have pro level photography equipment. This includes camera bodies, lenses, speedlites at the minimum. Other accessories would be useful. All equipment will be verified through the vetting process."
Top package is £430/day which seems pretty cheap to me (from a consumer point of view, not a pro myself) for which you'd have to produce 20 images/hour.
A MyBuilder type site would probably be really good, but this isn't it.
