I see you are looking for UK based photographers. Well, here I am, with my own studio, 30+ years' experience, extensive work in this type of product photography (see portfolio attached to my profile for examples), and access to models of a wide range of ethnicities, male and female, and all ages for lifestyle and fashion work.
This has to be a holding bid so we can start communications, but just as a guide $100 is the typical hourly rate here in the UK for such work on a one-off job. For regular work I'd be happy to negotiate if that's over your budget.
Please message me. I have a busy end to this week, but I'm much quieter next week. If you leave a comprehensive message with specific ideas and requirements, I will respond asap. I may be online but not at my desk.
I look forward to hearing from you.
Kind regards
