I might be off on some things but this is how i would price it.
this is the labor only, no materials, except the electric and plumbing.
gut kitchen, drywall, knock down "wall", remove all appliances - 1k (sell your applainces on CL save the removal cost, about 300 bucks right there)
all new electrical (including new wall panel) - 1.5k ? hard to say till you see how much is involved.
new flooring (slate/tile) - 800
14' kitchen cabinets (medium quality) - 600
mouldings on all cabinets - 300?
8' x 3' island - ? more info what's in the island? just an empty shell, or drawers etc.
granite countertops (install already paid for)
tile backsplash throughout kitchen and island - 400
install stove, microwave, fridge, sink, dishwasher, garbage disposal, trash compactor, wine cooler - 1k
ceiling lighting (6), under cabinet lighting - 400
changes to plumbing to accomodate a small water and waste line for the tank - 100
this is all based on electricians and plumbers i have worked with, and what my labor costs have been for previous jobs.
