Not wanting to be a spoilsport, but there are some things you should consider:
1. At 16, you'll need your parents' written consent before you team up with a stranger who contacted you through the Internet to go off and participate in potentially life-threatening activities.
2. In another thread, you write that you have no climbing experience. To climb in the Chamonix area you need to know about things like belaying techniques in rock, snow and ice; crevasse (self-)rescue; basic avalanche theory ... as well as being able to climb fast and safe at your chosen grade. I'd recommend joining a climbing club and learning the basics first. It's a fantastic sport, but only if you're up to what you're attempting; otherwise it can quickly go very, very wrong!
There's a BMC download concerning the legal side of things for climbers who are not yet 18 (and for their parents):
