Build a simple Google Chrome Extension

I'm looking for someone who can help me out with a Google Chrome Extension for children, called Robbie, an internet buddy in the form of a robot. He helps kids to browse more safely. The extension only has 3 functions (provided in a simple button, everything is already designed): activate the incognito mode; delete all history at once (already programmed); and block trackers on dangerous websites (like Ghostery, Disconnect,...) where the kids are alarmed about when they're on a website with over 30 trackers and thus rated as 'dangerous'.
