Hi,
I am a professional photographer/videographer based in Luton, Bedfordshire and would be interested in working with you to create your image/video needs. The fireplace I have is a gas one, so I don't think its ideal for what you need. However, I noticed you are based in Hitchin which is not far from me - if you have the stoves/scene set up I could shoot for you.
I think its unlikely you're going to have a photographer who already has the right stove set up, the other option is to hire a studio and set up a scene with stove etc but will require a considerable budget to do that.
If you would like to get in touch to discuss your requirements and if I can be of service it would be great to hear from you.
Kind Regards
Khalid
