Maybe worth giving Simon (aka springtide) a PM, as i know he has been on some shoots where models were used/hired
His PM is Here[url]
There are a few 'strobist' groups on Flickr (for different regions/areas), and I joined one of their 'gatherings' which I believe they got some models from 'Model Mayhem' (so I'm not registered there directly).
There was another on in Bristol this weekend, but I've had to pull out (my wife needs the time, so it's childcare rather than photography for me!)
@jmeryllman: Good tip about submitting a few 'good' photos. Thanks
@acemclynch: Let us know how you get on
I'd be interested in seeing how easy it is to arrange models etc, as trying to time the 'strobist' meetings with other family activities can be pretty difficult (they always seem to clash!). I do recommend the 'strobist' meets though, as although chaotic, they do give you some ideas from talking and seeing other people work.
