Android qualcom programmer

I am looking to hire someone to deliver source code for an android program that will use Qualcom libraries to read multiple markers/targets(in qualcom speak) and play a unique video file, with audio, for each marker that is detected. I can offer a bonus if you can make the program able to to remove a colour, in order to display the camera view in the place of the given colour(white is my choice colour, but that can be tweaked later by me).
