Could someone with experience, please give me an estimate for the price on the following (assume all items are modest; nothing fancy at all):

1) Installation of a new kitchen with new appliances.
2) Installation and purchase of a 2-sink bathroom counter.
3) Removal of a HUGH (3 feet across) Oak tree.
4) Repolishing of hardwood floors
5) refinishing and carpeting on stairs.
6) Some kind of "sealant" in a basement floor where there seems to be moisture and water coming in.
7) Approximate price to get a contractor in to estimate all of this for me (I live in Massachusetts).

Thanks so much!
