CAD MODEL

Hi, please take a look at this model. I need it Re created Properly or in a different program. Let me explain... I had been working with a artist previously on this Shield model getting it to perfection for many hours. Well i sent it off to the printers and the thing didn't print out right. The top surface came out all muddled up and not clean how these renderings show. I Talked to the printer he said that this model had bugs and i know its creation in the program Nx4 was very troublesome. I would like to see this been built bug free and will need a small test of the an engraved section before i send to the printer. I would like this to be made in a different program other then NX4. No payment will be made until i am am 100% satisfied that this will work. Due to the nature of the work and the workers on this site i am badly scared as i had paid full price for a model and plenty for revisions which don't work and are simply just good for looking at. It seems that the engraving is proving to be the hard part. I can send all Material files and the original measurements for the user to start promptly.
