Yoga themed shoot

NSFW

I always like to try and come up with slightly new ideas for my projects, one of which is a yoga themed shoot.  I have always been fascinated by models with dirty soles, and recently came across a Yoga video on YouTube where a yoga instructor is filmed talking to the camera and doing a number of poses.  What is remarkable is how naturally black her soles are, at one point she jokes about this   

I’d really love to try and produce a similar kind of video, so I’m looking for any models who would be receptive to a shoot of this nature.  I’m ideally seeking someone who’d be willing to quickly venture barefoot in a multi story car park near the shoot location to get dirty soles and then us shoot indoors.  I'd like to film as you venture barefoot in the car park for 10-15 mins before we do the yoga shoot back at my apartment in Chelmsford.  For the yoga side if you'd be willing to consider doing nude levels that would be amazing but also happy fully clothed in sportswear.  

This would be a paid two hour shoot, along with filming I would also like to take stills.  I've placed further afield as would also be happy to cover travel expenses.  I intend to start monetising the content I film, therefore would require any models to sign a consent release form and bring ID.  Please get in touch if this is of interest.
