Hello,
I may be replying to late and your DS might have found a placement already however my DD's close friend did work expirence with a tv company called "Company"!! It's in London on drury lane. They made programes such as skins, prisoners wifes, wild at heart etc. My DD's friend was 16 and that was fine - not to sure about age below that but you can try?:)
This may not be the thing your looking for but she went places round London delivering messages/news to other tv companies - sat on in meeting discussing upcoming tv shows and they asked her to come up with her own idea for a new tv show that she then presented to the boss!! - they wanted to hear ideas from what the public would want to watch !
It was fun working alongside the other "runners" going to different London tv companies - it was interesting to see how it all works
Hope that was some help but ofcourse this was just an idea !
