I used a jigsaw on the one side and my circular on the other for the long cuts. The jigsaw tended to wave off a little as to be expected. Shame you arent close enough, I have a saw you could have, just have to put a new blade in.
On another note, my next cab, the local Tech College has a CNC machine, and they are gonna let me bring my file in and cut the whole thing... As long as I do it IN CLASS and make a presentation for the kids... Sort of a trade. :-) If you have a college near by, it may be worth a shot... Of course I took classes there and I do a presentation for the students twice a year.. HTH
