Semantic themed keyword research

I need to figure out absolutely all (!) exact keywords and query phrases in certain theme for exact region. What is the best way to start such hard way? It's frequency doesn't matter.
Can anybody assist or help to set the right direction?

 

Can you give me an example? I'm not 100% understanding your question.

Also, are you familiar with Google Keyword Tool in Adwords?

 

For example: list of keywords and phrases for "Plumbing service" in "India" region.
P.S. I would like to make a job offer, but no still no permission/options to create threads in "Buying/Selling" unfortunatly.

 

1) Sign up at adwords.google.com
2) Under tools, select Keyword Planner
3) Click 'Search for new keywords using phrase'
4) Type in phrase, under targeting > location select India

That's a paid tool, how does it compete with Google?

 

There is no need to have active AdWords campaign for exact keyword search volume.
