zvi, I think you are preparing to make a lot of mistakes.

Having been freelancing for (oh my god) nearly thirty years now, I've come to see which firms make it and which don't. The firms which make it, have a sensible, well researched, business plan and go out to make the best possible production. Often they lose money at first, renting equipment and personnel and gaining experience.
The ones which fold don't research their market fully, make assumptions and try to do things on the cheap.

You can do a wedding with one camera, if you're very experienced and are only offering a "best of" type dvd. Anything else requires a minimum of two cameras. The only wedding company I'll work for uses three cameras, each manned by professional camera(wo)men and has a full order book.
Once you're known for being "cheap" you will always be cheap. You can always lower your prices for a special client but if you do cheap weddings, you can't suddenly jack up your prices when a customer with a bulging wallet turns up.

The idea of flipping the image is non-workable and daft. Komatoast explains why.

If you "start with low quality weddings " or do anything "low quality" your business will fail.

As for $7k being enough for equipment. A decent Dedolight kit costs more than that.

Torby and Turnmedia have "been there and done that" Komatoast is pointing out that most of your filming "solutions" won't work. Your company is one where I'd insist on payment in advance. Listen to what's being said instead of going on the defensive. A lot (a hell of a lot) of people start up their own companies thinking like you do, they all fall flat on their faces.

1. Get a realistic business plan.
2. Research your market properly (don't assume anything, get out there and research)
3. Make sure that you have sufficient finances.
4. Aim high.

Or alternatively.... Just make videos for fun.

Professional videography is a difficult and risky world to enter.
