Good lawyers don't advertise (always a golden rule) but are often mentioned in searchable online media. A good technique (imho) for lawyer selection in any given major city is to collect a list of the most prominent lawyers in the specialization area of interest, and interview all of them. There will usually be fewer than a dozen candidates if you've done decent research & narrowing down. At some point in the interview ask who they would personally recommend as a lawyer if they couldn't recommend themselves. Then see where the answers converge.
This does take a few days and in a country like India might take even longer. So if you need somebody in a few hours it could be useless advice. If you can find somebody for initial representation and then switch to somebody else later, it might be more applicable.
