But again Norty your posts and those immediately above skip over the costs of:
1. Huge volumes of smoke fluid
2. Travelling expenses
3. 4 nights hotel / motel accommodation
4. 4 nights / 3 days food and drink
Ok Al, I'll go over each in turn for you...
1. Huge volumes of smoke fluid
By your estimation, based on some wildly over-estimated need for 4 foggers running flat out, because you understand it to be a large festival, and not the grass roots festival it likely is.
Based on my estimation of it being a gig that they'd be happy with a couple of 1-2W 532 heads, and some well thought out placement, I think you could do the weekend on 5 gallons. As an expense, I'd be looking for them to pick that up. It certainly isn't, however, a $10k cost.
I guess they're looking for someone local if they have no budget. Now, over here, local is quite easy, but as they already say they're going to cover 'gas', even the larger distances involved shouldn't be a problem for the laserist should it?
3. 4 nights hotel / motel accommodation
This one had me falling off my chair. It's a festival... you take a tent, or sleep in your van/wagon. You are not a superstar, and as you're doing this for 'free' (i.e. not costing you anything, versus actually having to put your hand in your own pocket) because you 'want' to be there, being 'in amongst it' is all part of the 'experience'.
4. 4 nights / 3 days food and drink
Most festivals I've worked have either a crew catering facility, or are happy to pay basic subsistence, even for the freebies.
Now to the other stuff... 
Also, you mention the days when people provided lasers for free for raves, but wasn't it long ago you and others were moaning about how low fees were in the UK? In fact didn't you turn down a £100 1 night gig according to a recent thread because it was insulting? Do you not think you made your own bed? In relation to the £100 fee, a case of pot calling kettle black maybe?
Not at all. To be clear, it was a £300 'a night' gig, which happened to be a 20 hour long party in a squat (til 6pm Sunday evening - I do have a dayjob Monday, and I'm not getting any younger...), with a promoter who has a bad reputation. If it hadn't been him, and it had finished earlier, and the comms we had made me feel a bit easier about it, AND I wasn't putting myself and kit at more risk than usual due ot the venue, then I most probably would've gone out for the night and had a good one.
And its not the days 'when' people used to do stuff for free - it's going on today, all the time, just less visibly. I'm off to do a gig 15 miles up the road on Friday night for £250 because the promoter is someone I've known for a while, I like what he does, and I enjoy being involved in what he does, with the people. And thats lighting AND lasers. Am I killing the trade? I don't think so. The event has a small budget, and couldn't otherwise afford what I'm providing, so I'm not taking anyone's business away. I've got 5 projectors sitting around - I'll go and have a play.
As I've said several times in this thread, if the costs of doing this weren't so high, I'm sure someone would step forwards. However being a 4 day outdoor event with huge equipment requirements and very high personal costs to do the event make it unrealistic for most to do pro bono unless they're prepared to effectively pay $2K for 2 free tickets and do 4 days of unpaid work in addition, because that's just about what it amounts to.
As I've said a few times before, I'm reasonably sure it is in fact nothing like what you believe it to be, and neither are the costs.
I towuld be lovely for the OP to come back and clarify some of the details here, as it is, we're stabbing in the dark.
You are using Bonetti's defense against me, ah?
I thought it fitting, considering the rocky terrain.
