Hello,
It will be my pleasure shooting videos for your! The best time for taking shooting outside is towards the end of the day, during the last two or three hours of daylight, though we could get together any time: the morning, at night, during the week, the afternoon, on weekends.
I could bring you the sequences on a USB key the next day, or I could make them available to you through a web service and send you the link by e-mail so you could download them at your leisure.
I have a Nikon D600, which takes pictures at 24 megapixels, suitable for printing at sizes up to 16x20 inches, and far beyond if the resolution is upsampled in Photoshop or some other program.
Please don't hesitate to ask further questions, and do keep me posted as your travel plans to Paris take shape...
Very truly yours,
David
