I'm going to give you some different options. The cameras mentioned are fine, but, I'm of the opinion that a less expensive camera and better lenses will be usable professionally right away. The kit lenses are too slow to be used in low light without adding external flashes or other lighting. That will be your next purchase.
Buy a camera bag at Walmart, and a 8gb SD card from Costco or Walmart. Buy a brand name card, Lexar or Sandisk. No need to scrimp on a cheap card. My Canon DSLR burned out when I sold it to a buyer who used a cheap memory card that was shorted internally. (The camera was in Warranty, and Canon repaired it free).
You did not state a total budget, but a 60D plus a kit lens will run about $1200 at online prices. It comes with a 18-135mm lens which is just OK.
A basic camera with a good lens is a winning combination, and can be used for weddings and other low light occasions. This 17-55mm lens is one to keep - for a long time. Camera bodies come and go, but good lenses hold their value.
This is a refurbished lens, direct from Canon. It has a 90 day warranty and 14 day return rights, in the case you do not like it, or something is wrong.

This is a refurbished Camera Body direct from Canon, same warranty. The camera includes a 18-55mm IS kit lens which you can sell on craigslist, or even to another student for about $100.

The total price will run 352 + 944 = $1296 plus tax and shipping, and like I said, sell that 18-55mm IS kit lens, or keep it to put with the camera body when you decide to upgrade.. The teacher will know you are serious when he sees the lens you have chosen.

As a alternative, just spend $352 on the Basic Camera and kit lens until you are sure you want to continue.
Good luck!
