Any stats to support your 'largest' claim?

I only found 42 Escorts in the whole of the UK.

Ah different search, 418 apparently.

Just checked the Birmingham page and its packed to the rafters with agencies using their usual style of perfect, glossy, photo shopped images of models.
I could only see 3 independent types shoved right at the back on the last page.
