New to servos and need some help (very basic)

I am currently working on a new project in which i want to include 2 servos to open a door on the project when i flick a switch on, and then close the door when i flick the switch off.
In other words i want them to be in one position before the switch is flicked on, and another when the switch goes off. These positions need to be specific.
Can anybody point me in the right direction (website) or whatever where i can learn how to do this, i have been searching the web for ages and they all seem overly complicated for what i want to do.
Or can anyone simply help me and point out what i will need to do this and how to program the servos.

Like the title of the post says im new to the whole electronics side of stuff as im a small time PC case modder and normally just work on the aesthetics of cases, ive never put electronics in one before (other than lights of course). So simply information and guidance would be greatly appreciated.

thanks in advance.

The simplest setup might be to use gear motors with a limit switch setup like below.
