I read your quote and this is what WE spray foam insulation contractors have to deal with. Anyway, This is how I figure an estimate. First off Spray Foam costs allot! $2200 to $2800 per set of 55 Gal drums. Closed cell (2.0 @ 6.98R per inch set value) You need foam at 4 to gain an 27.92R or you could go with 3 and gain 20.94R. 3 was closer to your desired 21R so we will use it for our base.
