You can try a Glass Shop......if you can take the machine with the table that would help.....get an estimate first as it could cost more than you want to pay. The tables are made out of Lexan which is stronger and pretty much unbreakable.....BUT there is always a chance it could break.....and most Glass shops "won't" be responsible if it breaks and will ask you to sign a waver. Some shops charge depending on how much they have to cut down and then it has to be sanded smooth. All you can do is go ask....and it is best if you ask in person instead of over the phone so they can see what you need done.
We used to have a Glass Shop and the guy's cut acrylic often.
