pflow and 3Dmax

I need someone who has strong experience with particles and 3Dmax like pflow etc. I need an effect of some boxes on a floor that raise up into sky as many little particles in kind of a vortex. That means the boxes are the emitters but deconstructs into particles and dissolves! Length of the the deconstruction is around 100 Frames, the whole animation around 180-200! The basis is a max scene of the animation without the effect! I will need the scene back to render! It is very fast needed so it should be sure you have experience in this. Thank you very much!
