Simple OpenGL ES application on android

I would like an app that uses the cardboard sdk from [login to view URL] The project to edit is here: [login to view URL] I need someone who can edit the code (above) to have it display rectangles instead of the cubes. The rectangles should be stationary and spread out like a grid. In addition, I like to be able to add images to the rectangle (use any image of your choice as an example). I would also like to be able to select the rectangles by looking at it (just as in the demo project linked above) The next part is to comment critical parts of the code especially: 1. How to change the image use each rectangle, how to change the size of the rectangles, and where to insert code for actions to be performed when looking at a particular rectangle. I can code in java, and can get around the android sdk; but I no absolutely nothing about opengl. Thus I need someone who knows both, can get the job done quickly, and give me a quick explanation about customizing things. Please don't bid if your are not up to the task, and provide examples of your experience with opengl if possible. Thanks.
