Its a great idea Animaterra, but I think the above posts cover the main problems you will face. I think Noreen`s festival idea is splendid, it would be different and refreshing. I would suggest a way round having "influential friends a court" (assuming you dont have anyone in that situation) would be to video your work, put together a colourful and informative leaflet/brochure, and send that to festival organisers...........but do it quickly because acts are being booked and programmes are being finalised for this summer as we speak. Festival organisers like to work on sure bets.......thats why they tend to go by recomendation from people they trust. You have to get round that problem and the best way I can think of is to let them see your work first hand.....hence the video. For information and contact details of UK festivals try here.
Good luck and hope to see you this summer!!
