Cutting Acrylic into a pie shape in lower mainland?

[BCOrchidGuy]

Hi, I've got a 54 Gal corner tank and the stand has very little room in it for a sump. I've got a 10 gallon tank in there and it just barely fits but there is still room to the side so I was thinking about making a corner sump to fit in it. I figure this would give me a volume of about 16 gallons if I make it 12 in tall.
I need someone who can cut a pie shaped foot for the sump in the 20in long range and have the edges smooth enough to glue acrylic to.
If anyone can do this I'd appreciate some help. I've got a router etc but no attatchement for doing large circular cuts like I need.
