If the venue allows outside vendors to provide AV, I can save you
hundreds of dollars on your slide show.

All I need from you is a thumb drive- preferably a week before the event.

My "easy set up" projection screen is 48" high and 78" across, and needs to
be set up on a table or shelf.  I also have a large screen but it would cost
more and take 2 people and 15 extra minutes to set up.   It is 120" diagonally,
which is as large as any portable screen can get.   There are two options to add:
1. The venue may have screens for us to use and
2. The walls of the venue may be light colored and plain, which makes it
unnecessary to set up a regular screen if the angle is just right.

Audio:  If you are simply showing photos, I would prefer
to DJ the songs you picked on my DJ system- simply tell me the songs and
describe in detail when I should change to the next song.

If your video is made up of real video clips with audio, it is best to create a DVD.
I will then play it on a regular DVD player at my DJ table and run stereo audio
through my speakers and send out a video line to wherever the projector is
(if over 100 feet away, I will set up a speaker system near the screen).

A video presentation should be kept to 8 minutes or less, to keep audience interest.
I charge more for on-going non-audio wallpaper slide shows because of the expensive replacement bulbs required for my projectors.
