So what _can_ you do?
I'm sorry, but you are really not selling yourself well here. From what it reads like, you can barely program.
If you want a high paying technical job, you need to be able to quickly learn about new things. To be able to do that you need to already have some knowledge about the world outside. There's plenty of people able to install Exchange, but those will likely be outsourced as running Exchange yourself provides little advantage over some cloud service.
