Festival / Event Catering

[northwick]

My girlfriend is investigating the possibility of doing some festival and/or event catering. She's priced up all the equipment and has costings for the food side but one thing that is quite difficult to find the 'going rate' on is pitches at festivals / events. Most seem to require you to fill in loads of applications including copies of Health and Safety certificates etc, which at present she doesn't have.

Does anyone have any experience in this area?

How much would one pay for a pitch at a huge event like Reading Festival? Or something still very big but a bit more upmarket like The Chelsea Flower Show? Or what about something a bit smaller such as a large town's Beer Festival or something like the Ragley Hall Classic Car Show?

Obviously costs will vary according to event size and quality of location within the site (as well as if it includes electric or not) but would really like some rough numbers if anyone has any insight?

Thanks in anticipation.
