^^ Damn, got there before me...
That said, there ARE festivals of the DIY kind, where people do go, and provide services, for very cheap and/or tickets (although normally an allocation that can be sold to recoup cold hard cash), but you need to tap into potentially a different market of providers, and have a reputation that the event is going to be totally awesome and worth being involved in.
The important part is ensuring that everyone of your providers perceives every other one to be gettign the same treatment/deal, otherwise it can get awkward...
You are using Bonetti's defense against me, ah?
I thought it fitting, considering the rocky terrain.
