Listen, no offense, but... you don't need to start a new thread every time.
Price are impossible to give over the internet. None of us can see you house, or know what the various regulationas are in your area, or how much a dumpster cost, or what the going rates for labor are... all of that stuff varies tremendously depending on where you are.
Get a bunch of contractors to look at it - the usual rule is a minimum of 3 - in your case, since it seems like all this is new to you, I'd recommend a few more than that. Thenm you can just compare their prices.
But don't just ask for a price.
Ask for references, and actually call those references. If you can, go see some of their past work (not always an option, as clients have a right to their privacy, but it's worth asking).
Get the contractors' license number (here, it has to be in all your ads). Get in touch with whichever government agency handles licensing in your area, check the contractor's track record. See if they have a record of complaints, etc.
Ask each one of them to explain how they want to do it, and why. Each interview should teach you a bit more, so that you better know what to ask the next guy.
If anyone wants to just go over the old siding, ask them how they're going to deal with flashing around the windows.
If you hear someone use the words "drainage plane", stop looking, hire that one.
I assume you just got this place? Often a good place to start, instead of the yellow pages, is to ask your neighbours if they know a good contractor.
Where in NE are you?
