Flat Styrofoam wanted FREE - Thank you! (KCMO)

I need lots of flat styrofoam for shipping fragile items in my small business.
I need flat pieces of styrofoam that are similar shown in the photo.
1/2 inch or 1 inch or 1 1/2 inches thick.
I need pieces that are 12" wide or larger.
Large sheets of flat styrofoam are great! Please no irregular shape styrofoam as shown in the 2nd photo.
I can come pick them up at your home or business or I can meet you somewhere.
Thank you so much! PS I also need styrofoam peanuts.
If you have 2 or more kitchen trash bags full of clean peanuts I would greatly appreciate them.
The peanuts need to be clean: no mouse droppings or mold, etc.
Thanks so much!
