Could you ask for a parenting coach? That sounds like what you want. They will usually do some observations, chat with parents about what *they* feel are the biggest concerns/priorities and also provide referrals if there is a deeper issue which requires counseling.
That said, there isn't always a standard qualification procedure (which I am aware of, in any case) for certifying people for this job. Just like a life coach, you could get someone amazing or someone who you don't really jibe with. Do your research.
