Hi there, I can have your models done in sketchup (.skp) file and also export as .STL, .3DS, .OBJ, .DWG, etc.
I do not use rhino, but can get the exact same thing in sketchup. If you are interested, please contact me to discuss more about this and I'll tell you my final price once i have reviewed all your files and seen how many are there to do.
