my parents just had the sill plates on their new house done with spray foam while the insulators used pink fiberglass in the walls, rigid on the foundation walls and blown in cellulose in the attic. It cost them $4/sqft to have the spray foam done but I went through there afterwords and the crew did a good job on the first pass.
My parents got back quotes as high as $7/sqft to have the plates sprayed.
