Video projector with Power Point would be the way to go....if money was no concern.....but!
Mike I think you said you have a three screen, and I think you are missing an important opportunity to increase revenues without sacrificing the quality of your presentation. But if you wait until you can plop down 3 to 6K for a projector and computers, learn a new software application, you could find yourself behind the curve.
I bought Kodak slide projectors, and Corel Draw. I draw the slides, email them to a place to have them imaged, and sell the ads for $250/quarter. I have a three screen and an am in a very small town, but last year I grossed over 20K in additional revenue.
So I think I present my shows with the Film done Right concept, I keep concession prices " Family Friendly", have raised my ticket prices twice in 8 years, try to pay my help above poverty level. The thing is, the utility company, insurance company, concession supplier, film distributor...list goes on....has a different view. They increase prices lowering my bottom line.
I get really tired of hearing projectionist wannabees say how the ads ruin the presentation, let these guys plop down a cool million to build a theatre from scratch and see if they have the same thoughts every friday when they scramble to meet payroll after grossing about 4k for the entire week and you are on a 7 day with some guy that doesn't care if you show his product or not.
This business is a labor of love, and anyone that owns or manages a theatre, that hasn't gone in at the back of a show to simply watch the audience's reaction to a particular scene, doesn't understand this love.
Consider the slides, keep your business healthy, and heaven forbid...actually turn a profit, because everyone knows if you sell a ticket for 6 bucks, you keep 5 bucks for yourself.
wow...I may have had too much coffee....
anyway just a thought
