I'm looking for some basic tracking in After Effects -

I have a personal music video on the go ... I have been tracking the shades on the guy on the image below .. Thought it would be fairly straight forward but struggling .. So I'm looking to see if anyone would be interested in doing the tracking and supplying an AE file from where I can just attach a Null and add from there ... I dont have a cost in price obviously will pay for your work .. There probably around 2 minutes .. Guy wearing rectangular shades .. shot on green screen .. not moving too much or fast ..... Example frame below. Any question please give me a shout .. thanks
