[Greg Ball] “How long would you estimate that the editing would take? “
I doubt anyone can answer that unless one knows what exactly the client wants or what budget the client want’s to stay within. I’ve great things done with stock footage with After Effects, Combustion, Flame, etc.
If you’re just going to dissolve between stock shots, add vo and a logo/id at the end it could be 4 hours depending on the tweaks.
[Greg Ball] “How much would your charge be for this spot?”
There’s not only the cost of the clips and the music but the time you spend finding them. Then there’s the cost of the VO. How much is your time worth in your business model is up to you.
You don’t say how much the music costs, how much the VO person costs, who’s providing the script.
If you’re acting as an ad agent there’s the money you make on that too. If it’s a BIG buy you can go cheaper on the post production side.
IMHO if the client is spending $2000 plus your markup on 8 stock shots, they’d be better off hiring someone with a good DV or HDV camera and getting something custom shot in a day or two. It may not look like 35mm film or HDCAM but at least it’ll be about their business.
