Xbox 360 is Broken No Warranty, Need Help?

So, my Xbox 360 is broken. I am not exactly sure what is wrong with it, but it won't play any games even if they are new in mint condition. It turns on but when I try to play a game it says the disc is unreadable, and the disc drive make an annoying sound for a few seconds. This is the problem: I don't have a warranty, so I am probably going to send it in to microsoft to fix it for $100. But, I have opened the Xbox and taken the stickers off in a failed attempt of fixing it. I know that removing the stickers voids the warranty, but will they still fix it if you pay to get it fixed? I don't see why they would not do it if you pay them, but I am not sure. If you know I would very much appreciate your answer.
Thanks.

Suggestion:

They should definitely still fix it if you pay – it only voids the warranty unscrewing the console.

You should ask them the general price of something like this, you might be better buying a new console if it's more pricey as they are cheaper these days.
