Physically Fit Black Males for Concept work

I am looking for Black Male models with physically fit bodies for a concept shoot I have planned revolving around black bodies and anatomy. A lot of simple body contorting and playing with shadows for this one. I’m expecting this shoot to last around 4 hours at best, I have a studio booked for the 11th August in London. I can offer a rate of £25 per hour and cool images thank you.
