how much to install kitchen cabinets?

[canadian_hustla]

Ok, so my wife and I are doing some renos, we bought some premade kitchen cabinets and how have the daunting task of demolition and installing them.

What is the average price for installation? Kitchen is 8x10 i think + island

Also, we bought some granite countertops but will need to install those too. What is the price for installing granite? approx 36sqft.

Thanks in advance!
