Nikon D3100 Hairspray contact

Basically my mother borrowed my camera and put a bottle of hairspray in there as well. NATURALLY the cap came off and covered my camera. I have been using the manual focus because the autofocus is not working.

Auto focus - The sensor light comes on and it makes a little noise the first time you press the shutter button (as if it is trying to focus) but the lense will not move. I have checked inside the camera and all looks normal and untouched by hairspray. I'm wondering if it may have just gotten inside the lense? Or if there's anyway to open it and/or fix it.

Buttons - The tricky part (as I CAN in fact manually focus if I have to) is that the buttons also seem to be shot on the left side of the camera. All except view mode. Not working: Menu, both zoom buttons, and info. I can't even get into the menu to change settings.

I understand that this is terrible that I let this happen to my camera, I just want to see what the best way to fix it is or what parts need fixing. I brought it into a shop and they said I had to send it in to have them look at it. THEN send it back in to have them fix those specific parts. All of this wracking up to the total of a new camera.

Help if you can, I will try anything! I have only had this camera for 1 year.
Thank you.

Added (1). I'm aware that that is what must have happened. I'm just wondering if there's anything I can try to fix it. Spending a ton of money on a new camera isn't really an option right now and if i'm going to do it I would like to try everything that I can before hand.

Perhaps your mother can buy you a new camera.

I'm sure that hairspray has gotten underneath the buttons and "glued" them to the case. Same thing with the focus ring I bet.

You really need to send your camera to Nikon for a thorough cleaning, something called a CLA (clean, lube, adjust) which will cost about $250

Your mother needs to pay for this repair.

In the future, NEVER let anyone use your camera.
