UK contacts websites

[fenghuang]

Now that Gumtree no longer does Personals ads, does anyone have any good recommendations for where to find UK based NSA contacts online, without having to pay membership fees for AFF or similar.

I'm contemplating a little photographic project that needs a couple of assistants.

I know Lit has personals but I'm looking for something a bit more specifically local, just to up the chances of finding people interested in helping me out.
