This website lists when events are on, and we are not involved with organising any of them. In most cases, the information we have listed is straight from the event website or Facebook page.
If you have a food truck or other similar service that you want to take along to an event, then you need to touch base with the event organisers directly; sorry, but we can't help you.
The best way is to look for events in your area and look at the event details. On each event listing, you will find links through to the website, contact page and/or Facebook page for the specific event. Click through to one of those and contact the event organiser there.
