Hi,
My name is Jack Davis and I am a Los Angeles based mechanical design engineer currently working for spaceX but I like to pick up freelance gigs, such as yours, when I can. I would complete this for you in SolidWorks 2012 and have done a lot of jobs like these where it is kind of a reverse engineering for documentation. Some of my previous work can be seen on my online portfolio here: [login to view URL]
Thanks, and I look forward to hearing back,
- Jack
