How best to use TM as a producer/director/journo for documentaries?

Hi all, I’m was wondering how best to use the site with a view to finding documenary based work in the UK. I’m primarily experienced as a producer and journalist with some direction behind me as well. Most of my contacts are in news or short form, so this is a new step for me. Have people benefited from the PRO service too?

All advice most gratefully received!
