Im looking for kwd research longtail low competition

Hi, I’m looking for detailed keyword research for premium private therapy clients (high net worth) in London, Dubai, New York, and Los Angeles. The focus is on anxiety, trauma, PTSD, and depression — with keywords like “private anxiety therapy,” “hypnotherapy for PTSD,” etc.
Can you provide local search volume, CPC, and competition data by city/area, not just national estimates? And can you highlight the top 10–20 commercially viable keywords for each region?
This is not for SEO — I need PPC-level keyword data (local search volume, CPC, competition) so I can decide whether to run Google Ads in these markets. full brief in google doc not sure of what costs are let me know?
