Professional photography for fitness blogger in London/Herts

I am interested in finding someone who can do a 2/3 hour max shoot in a range of different locations to a very high standard for my work as a personal trainer. They must be able to shoot in a range of lighting conditions, have appropriate equipment, be creative and have a portfolio that displays their range.
I work with a well known sports brand and the shots should be able to reflect both myself as an individual athlete and the apparel I am wearing. If successful, the opportunity is there to shoot on a semi regular basis.

I am looking for a 50-70 useable shots in a variety of clothing, performing different actions and with a clean, professional, Nike'esque look whether raw or mildly edited.

Thanks in advance
