As a serial offender with this kind of damage - Here are some rough estimates. New bed knife blade about $40+ but it needs to be bed ground.
Straighten (minor) reel blades bends and cylinder grind $ 120+
Or if you have done really bad damage and need new sole plate (the cast iron backing to the bed knife) - then you will very likely need reel, bed knife and sole plate =$540 - see attached link to eBay for parts suppliers on eBay

Frankly - I would be surprised if your damage is too serious - getting wood jammed in the blades is most likely to have simply bent the bed knife blade and maybe one or two reel blade segments.
I am still recovering from a poxie builder who spilt a whole box of stainless steel screws from a scaffold on to my lawn - 18 months later and I am still occasionally collecting one = divot out of both reel blade and bed knife GGGrrrrr
