Script/app for 3ds Max

Hi, Im looking for programer that would be able to create little app that would load simple scene (3ds, obj, more or less simple objects as Boxes) and based on defined source possition evaluate visibility of given position(s). Best option would be script in maxScript for 3Ds Max. It should be actually script that would evaluate enviroment and simulate sun rays coliding with leafs of vegetation (areas) and sum amount of rays colided with each area. Therefore it would generate kind of random amount of illimunation of leafs. Hope you get it. Based on this app/script we wold estabilish further cooperation.
