gadkins, Welcome to the board, I had to move the post to "The Business of photography" area you should get more input here.
As to your post.
I have had it with working for others and making them money only to be told I am no longer needed.
I totally understand, I've been there and done that.
More Power to you!!! The hardest or scariest part is that it feels like stepping off a cliff not knowing how far that cliff gos. It may be just speed bumps or a jump out of a airplane. Either way if you set your mind to it and work really hard you can do anything.
First thing I would point out.
Weddings are a once in a life time, low light, fast action, stress full, etc.. Photo shoot. It could be a real headache if you don't have the skills. I would tell you if you are just starting out try to stick to non-weddings, like portrait work. Where you have time to set the shot the way you want it, where you can do it over etc...
You really need to have a good portfolio. If people can't see what you can do they will go to someone that they can see. Start building a portfolio. Mix it up as much as you want but less is more.
utilizing the internet:
Well this is a big one. After getting a good Portfolio you start showing your stuff to everyone. If your portfolio is not good don't do it, it can harm you more than help you. (post some images we can help) Take some classes (photo and marketing etc) (not knowing your photo skills this is good for everyone) Online ad can cost you $1000's each year with no promise of any return. So start slow, start marketing yourself off line first (maybe have your port online if you would like)
As for your camera:
I will leave this to a Canon guy, but I don't think it is up to par for what you want to do.
And like John said "this huge competitive business" don't sell yourself short but remember that there are 1000's of photographer and more every day trying to make it. Stand out! Be different, What makes a customer pick you over others? Don't make the mistake that a lot of newbies do and under cut prices, You don't want them to like you just because your prices but your skills. Plus cutting prices can lead to "He's not that good", "Give me everything for nothing", "I'll just copy them" etc.
Hope This helps.
