Most parent coaches work with parents over the phone or video call. I’m sure there are some that would travel to your home for a few days and do in-home work with you (speaking for myself, I would but travel would need to be covered). If you google parent coaches you’re likely to find someone — just be sure they specialize in ADHD.
The only therapy I know of that goes into your home is ABA, typically used for autism and I’m not a fan. I prefer looking at behavior as communication and implementing parenting approaches that are effective and helpful. Our kids need to learn problem solving skills and self-regulation more than how to comply with a strict set of rules.
