Hey John, just a thought but if you've not found anyone for your documentary, you could try the Guest Services staff at Chiswick Business Park; come out of the Gunnersbury Tube, and cross the road. Immediately there is a series of about 9-14 modern buildings set around a park including a man made river. The guest services staff all wear grey trousers and bright yellow tops, and by memory a large number of them are Polish (I believe at one stage the employers were providing English lessons as part of the employment perks). Several I spoke to while working there posessed degrees from Polish universities, but were working as cleaners etc while building their language skills.
