I have a project coming up that I want to film and would appreciate some advice on hardware. It's a vehicle restoration project and will be filmed in a garage. It will take 3 weeks to complete and I need to film 8 hours a day from 3 angles (so 3 cameras). I also want to carry a 4th camera around with me and be mic'd up so I can interview the mechanic. I believe I need a camcorder as these are able to film for a longer time, but beyond that I don't know a great deal! Any advice would be much appreciated.

Many thanks
