I’m interested in starting a small (on location) photography business. I have several small digital cameras, but would love some opinions from owners of different brands. Would mostly be for group/single/wedding photography. Stills and action.

A pro who is ready to start their own business would already know exactly what they need and have the skills and experience to back it up. You clearly do not.

Please be realistic and learn the ins and outs of photography and business before jumping into making money. It’s not as simple as you’re making it out to be.

Would this all be considered "Digital Media"?

Yes it is! I use all those programs and I’m a Digital Art/Graphics Art/Film producer major… and yeah those are part of Digital Media.
