Fix illustrator files

Hi, I need someone to convert the 'clipping masks' in the attached Illustrator PDF file into just normal lines. So the final product I need is an Illustrator file that looks exactly the same as this one, except not using clipping masks to create the images. So you just need to release the clipping masks and then trim back the background to the mask line using normal techniques. The reason for this is I need to export them to Autocad and the clipping mask does not export properly to Autocad - I am left with the whole background. I am hoping to pay $35 for this. I need it urgently so I will be choosing someone in the next 24 hours.
