Looking for a declutter/deep clean company

Hi all, I’m looking for a company or individual that specialises in cleaning depression homes. I’m not looking for judgement i’m looking for someone who can help, this is for a single person who lives on their own and does not have the means mentally to deal with their own mess. It’s gotten to the point where I do not know where to start and I just need help with a complete reset. I am talking large amounts of cat hair, decluttering, and extreme deep cleaning.

Please hold rude comments and judgement, I’m not happy to ask for help and admit things have gotten this bad. I just need resources and advice , thank you
