the way I see it going is the film company will set up the cameras in a Hotel conference room. The room will be similar to a living room in that it will be carpeted and have upholstery and curtains.
each person will have 30mins film time within the room to do as they wish. eg;
you could spend 10mins talking about your company, 10 mins outlining how you clean carpets, 10 mins discussing all the different services you offer, 10 mins doing a demo of how you remove a coffee stain etc..etc its really up to you
they say they can put the video in any format you want ( but some formats will cost a little extra)
I don't know the full details but I would think you will own your 30mins of material.
the days cost will be the same weather its 5 people or 10. i'm giving my self a budget of £150, if it goes over this I'm out,
what I need is 10 people to say they are definitely interested then I can go back to the company and start getting a more detailed programme.
