Insulation Contractors

Has anyone recently priced having their attic insulated? My attic space is roughly 2200 sq feet, and completely decked. Home was built in 2000 in the LC, Dickinson, Alvin area, and we’ve upgraded mostly everything in the last 3-4 years (doors, roof, windows, ac units) with the exception of the attic.

Just wondering if anyone has a recommended company/contractor. I really don’t want to rip up all the plywood decking.
