Go to a granite yard in your area, HD and Lowes will never be the top place for a QUALITY stone. Granite is measured in classes or levels depending on your shop, HD and them mostly specialize in class 1 (lowest grade) stones and charge class 2 to 3 prices for it. Go to the yard and pick out YOUR stone(s). With 61 sq ft you are probably looking at 2 slabs. Once you have your stone picked find a good fabricator. We got WILDLY different prices, the most expensive being almost 2500 more then the guy we went with.
Don't think the free sink is a good deal, it's a cheapo stainless steel contractor grade sink usually, we have one in our current house and it SUCKS to keep clean. We bought a sil granite sink off of Amazon for 100 bucks and had them cut to that when we did the other house.
We had a one slab counter (dealt with an extra seam to avoid buying the second slab), bought a class 4 stone, and with fabriation, installation, and a nicer edge (thrown into the deal) it came to 2200.
