Seeking possible contributions for camera upgrade

Hello, Thank you for taking time out to read about my project. In the end I hope it is something you would consider helping me out with. But Thank You in advance again for simply taking time out to read this.
My name is Andrew Caccia & I aim to become a Professional Music Video Director/Producer for major artists appearing on MTV and what not!
I've shot many music videos for local artists as well as multiple weddings, concerts, even high school football games. 
I currently use a Canon Rebel T2i and have been using it for almost 4 years. My hopes and goals are to raise enough money to land me to the 5D Mark III. Having this will allow me to not only better my work, but be able to start rising my prices on my video rates, being able to make a steady amount to put away for film school in hopes to become a music video director! As of now i charge very little to nothing for a video, all in order just too get my name out there and well, because i just love to film!! Its almost as if its a part of mw!
I am working. But its  hard to save outside that box being that i am paying for school all on my own as well as other living expenses. Which is why I'm shaming myself and asking random people, friends, family and co-workers for help. I would love a camera that is fast enough to capture dramatic, clear, vivid images in any situation given, I like a camera that has a high ISO for low light situations.

If you would ever like too see my work or contact me, i will list my email and youtube channel!
