i'd suggest you email '3 daft monkeys' for info & advice
and potential networking mates.

They are one of my favourite recent 'folk' bands
and include a very charismatic female fiddle player
who brings east european/klezmer influences into the mix..
& they gig extensively on the UK / Euro festival circuit

Of immediate practical use to you, they have a message board at their site.
