Yellowish in color???? If so then you will probably not like the prices of
getting the stuff yourself. I have had foam sprayed into block walls
before that worked well.
Problem with foam is the "good stuff" is a two part mixture and requires
equipment that is expensive for a single use.
I suggest you contact some local contractors and have them bid the job.
In lew of that try this site. Do the math carefully. The site is mostly
board feet not cubic feet.

You will quickly notice that the price does not change very much. ~a dollar
per board foot.
Is there any reason that you can not just stuff fiberglass into the areas
and use some spray adhesive? Most of the heat goes up anyway.
