I use Bali and Lowes - Lowes got in house measurement for $40 and installation for $95 up to 5 windows (just add 55 if 40 paid). The Bali cellular shade I chose can go as big as 120"x96" one piece blackout and control with somfy battery pack (I think light screen will be even lighter/easier). You can do the measurement yourself and get realtime quote online too. The price with online quote and physical store is very close within $100.
