Thermal Line Windows, Silverline Windows, and Western doors

[Fropa]

I'm in the La Crosse area of Wisconsin. I had a contractor recommended to me who I'm going to get an estimate from on Monday. The companies website says they use Thermal Line Compozite Windows, Silverline Vinyl Windows, and Western Entry Doors. I will be replacing a 10'1"W X 4'3"H living room window and a 3' X 3' garage window. I may also replace my entry door and storm-door plus 2 sliding patio doors. Where do these products fall in the quality category? Is there a certain model or series in their lines I should look at? What would a reasonable price range be for the size windows I need? Any other info I need to know?

Any contractors you could recommend in this area I should request a quote from?

Thanks for the help.
