What sort of volume do you envisage?
The standard Epson, Canon, and HP pigment ink wide format photo printers would be in your price range, but they are not really designed for what you want.
Ink costs would be in 50 cent/sq ft range, and inkjet coated paper is way more expensive than the uncoated stock you can use with other printing techniques.
They are also not designed for continuous full bleed printing. The overspray ink ends up on sponges either side of the paper and builds up pretty quickly into a mess.
