I'm in the similar business and I use epson 11880 with EFI RIP for my work (fine art/ giclee) call it whatever you like. Prints are amazing but expensive, I charge 120-200 euro/m2 for prints on canvas.
For commercial work I would go with epson GS6000. Friend of mine is having one and prints are excellent and not expensive approx. 8 eur/m2 on canvas. He is also using EFI RIP.
