Front teeth severely misaligned causing damage and massive overbite.

I have been told that at least my two front teeth needs root canals done due to the angle they are at to each other and it's impossible to clean so they have a large cavity. My teeth on each side of the front are also misaligned and damaged. My canines stick out further than the others and makes my whole smile look horrible. I was told braces weren't an option without surgery to correct my lower jaw. How can I fix my front 6 teeth without spending thousands.
