I work for a remodeling company. Sometimes we recommend that our customers pay to blow insulation in hard-to-reach areas that we are working in anyway. It doesn't add much cost to the project and it saves people the hassle of doing it themselves.
So...if you are energy conscious, look into cellulose (sp?) blown-in insulation. You don't need to pay a contractor to do this process it is EASY. The material is cheap and made from mostly recycled materials. It comes in $10 blocks from Home Depot and they will rent you the blower. It is very easy to do yourself: depending on thickness, it takes about an hour or so to cover a large room attic-space. You can go over old insulation if you like.
It's also cool because you'll see a lot of ground-up plastic shopping bags in the mix. Best part is that it doesn't make you itchy!
