Accidentally spilled coffee on my MacBook Air.

I accidentally spilled coffee on my MacBook Air keyboard.

What I did after spilled coffee on my MacBook.

1. Turnoff MACBOOK immediately.
2. Remove the coffee from keyboard by using Cotton Cloth immediately.
3. Turn the computer upside down for 24Hrs at Room temp.

Problem now I faced:

1. Trackpad not working
2. Camera Not working
3. Sound not working.

What to do now ?

What will be the estimated cost to fixed this issues.
