Nesting/CNC plugin for illustrator?

[DingusMcFeild]

I have 3 or so hundred different shapes I designed in illustrator that I'm using a CNC machine to cut out of 4x8 sheets of plastic. Does anyone know of a plugin for illustrator that allows you to automatically layout and nest shapes to optimize space within a given area?

I have a similar problem with irregular shapes (with clipping mask applied) that need to be nested on pvc of a roll of 1.50 m width. Need some help, thanks.
