This thread is a perfect example of why we need to stop playing the "how much do you charge" game.
There are WAY too many variables to judge all of us on the same scale.
As for the OP, I would probably admit to the client that I did not know the music well enough to do it justice...
but I would be more than willing to work with them to make them happy.
I also would NOT worry about their request that the music not be too loud.
Personally, I did not interpret that as the client wanting low volume. (that's silly, why pay someone to play music no one can hear?)
I'm pretty sure they just don't want people's ears to bleed. ( "I was at a wedding recently and the DJ was so loud...")
As for TIME, that's another local variable.
Around my hometown, 99% of the venues sell a 5-hour package. (1 hour cocktails, 1 hour dinner, 3 hours dancing)
Of course, that does not include clients who have their ceremony at the venue. (and there are a LOT of those)
I sometimes book gigs that last 6 or 7 hours at the same rate as 5 hours.
As for Taso.....
knock it off...you're making us look bad!
