I just heard back from Peace River K9 Search and Rescue (PRSAR). They are located in Southwest Florida and are a non-profit 501(c)(3). Peace River K9 Search & Rescue Association With regard to how much they would charge to search a 2 mile radius of land in Champaign, IL they said: "Thank you, we never charge for our time but in order for us to come up you would need to purchase the plane tickets and housing for 2 searchers( cadaver handlers work in pairs) and the areas that need searching would need permission given by the property owners. You might want to see if you can locate cadaver handlers closer to you and avoid the costs as we are in Florida. Adivse is always free!" That's what I got for now.
