US Based Dev for - Raspberry Pi 2 - Python Home Security System and such

Hello, I am trying to learn basic development and would like to build a home security system on a Raspberry Pi 2 with very basic input and outputs with the ability to email me if alerted. This is step one of the project that may grow into a home automation system. I will do the hardware side, but just want to have a program written that will allow me to remote monitor my house (via website, app, etc) and have the following inputs and outputs: - If a GPIO (input) trigger (switch) is tripped it turns on a light or alarm (output pin)for a few seconds and sends me an email of the pin or switch name that was tripped. I would like 3 of these switches that will trigger the alerts - PIR Motion sensor should also trip the alarm - Would also like to monitor the temperature and humidity of the house (I have the sensors) and alert me via email or pop-up if it exceeds a range. - Optionally, would like to turn on a little LED remotely I would like this to be done in Python (very well documented) so I could learn how it works better. If this works well, there will be much more on this and many more electronic related projects that I would like to find someone to work with. Thanks. Joe
