Hello, this is my first time posting here. Anyway, someone I know has recently asked me to produce a digital photo slideshow for her daughter's graduation party. The idea is that I would take a number of (digital) photos, and then set up a slideshow that would be projected onto a wall during the party. I've been taking pictures for a few years now (conventional and digital), but never professionally, so I have no idea of what to charge for something like this. I figure I might end up using somewhere between 100-150 pictures. Does anyone have any ideas on how much something like this should cost? Any information/advice would be very helpful. thanks!
