You should contact a local contractor for an installed price based on your site, unit sizes and code requirements. They will get a price from window suppliers, add engineering, demo, framing/trim, installation, painting, etc. FYI the end wall pictured is actually 7 windows; 2 dbl hung windows on each side with 2 transom windows above, plus a fixed picture window in center with a transom window above plus a matched half round unit above the transom. There are very specific engineering and framing requirements for an installation like this due to the designs lack of wall shear sections to provide lateral bracing support. Common building design requires about 2' of wall space on each side of a corner or very specific designs with bracing for retrofits.
