Digital print job (wedding invitation) *double sided, registration important*

Hi! I'm in Bushwick looking for a local-ish resource for digital printing. Something like a big Konica or a Xerox which can print double sided, color, card stock. 80 pieces of paper which I'd bring. If it helps, here's more info: each invitation is two pieces of paper folded, making a booklet of 4 leaves/8 pages. Registration is important b/c we're going to be trimming out a shape (it's not a heart) The registration does not need to be dead on b accurate, within .125" inches would be ok. Let me know if you can help! Rate based on per hour or per print whichever makes sense to you.
