Hoarding Services

Hello! I’m looking for a clean up company that specializes in hoarding. My mom passed away and my sister and I are trying to move my dad out of the house. It’s about a level 3 hoard, maybe a 2. Have you used a company? Do you know anyone who has? We would like to go with someone based off good reviews because we do not know what we are doing. Also, if you have, did you pay for it completely or are there programs that help finance? My dad is in his 70s. Thank you so much!
