I am looking for Web Researcher

I am looking for a part-time research expert who can deeply study Any provided website and explain how their service works in practice. I do not want a generic AI-style summary or basic information from their homepage. I need a clear, human analysis of their services, workflow, business model, and practical lessons that a niche expert firm can adapt.

I only need research expert. not beginner or junior.
I will explain details in meeting.
