Replying to Mounting ski bindings

Okay,
So I have a pair of 10 or 09 K2 Extreme skis. When I got them the bindings were already mounted back in a more freeride position. I want to mount them center since all I do is jump and grind rails and do tricks. I took them to a local ski shop and they said they could not mount them because the ski was to wide (psst stupid people). So I was wondering if I could make my own jig and mount them myself. I am very good with my hands, some of the things I have done: Converted a full suspension mountain bike to single speed. Made a a sick ski bike with no plans. Created countless props and trinkets for movies working biking skiing etc. I also fix pretty much everything around my house because I am so good at this stuff. So from what I have said would I be able to do it, I have done hours of research about this. Also I do have a back up pair of skis if something were to go wrong.
