You charge extra for a wireless mic? Really? That's been a standard item for what...20 years for most of us?
Yup sure do....Believe it or not very few in my market use wireless so they way I figure it is it cost me $500 to give a service that most don't give I should be able to recoup my money. If the Wireless is standard why not uplighting or projector and screen?
Here's the other part my market sucks as far as price is concerned my average starting price last year was about $450 and I am one of the top 3 highest priced in the market so I start at a base of 4 hours with 3 lights and a full sound system and upsell anything else they may need. It works out good for me and good for the client they aren't buying a package to get one thing they need and 5 they don't
