I may be shooting a paid gig here in a couple weeks but I haven't done any kind of hourly rate + add-ons, just a flat rate for time, processing and a CD. I don't have a lot of details, but it is a 70th birthday party for my cousin's co-worker's mom. They'd like me for a couple hours to shoot random photos of the party then process them and provide them a CD/DVD of them. They also asked if I could create a slideshow of old photos from the 1930's that would display at the party. I can easily do this as long as they provide a digital scan of the photos. If they require scanning and converting, I won't be able to do so. I'm no pro and don't advertise myself at all...this was completely word of mouth suggestion from my cousin. So for say ~4 hours, processing & slideshow, what sounds like a reasonable price to charge?
