Welcome to MD, OK in your post you are asking for a lot of things here...
1 - 'Canon photography' ?? Are you needing help to know what the buttons do on a Canon, or just the basics of how a camera works? (ie. exposure, ISO, shutter speed...)
2 - 'working as a photographer' ?? If you are working - is it with a paper or for your self?
3 - 'break-in to the business' ?? Not sure what you are asking for here?? Are you trying to start your own business, looking for help in a business plan, or looking for another person to shoot for?
4 - 'really make it' ?? If I get this right you are looking to support yourself by doing just photography?? You can do it but it will take a while from the sound of your post...
Do you have a portfolio since you have been 'working', if not that would be a good first start.
The CSM college offers basic photography class.
Do you have any idea of what type of photography you are looking to get into?? (that will help you decide what type of gear you should invest into)
Hope this helped a little...
