HELP! HOW/WHERE DO I REASSEMBLE MY LAPTOP?

I took my laptop apart with a screwdriver (I kept all the parts) and it's been about 2 years since I've touched it. I finally decided to go to GeekSquad to reassemble the laptop (to just put the pieces together) and they're going to charge me $200 without tax! That's a ridiculous price, IMO, so any input on this would be greatly appreciated, thank you!

I am able to put the screws in the right places, but unable to redo certain parts of the laptop i.e. the keyboard and mouse sensor cables.
