PS5 cleaning and liquid metal repair in India

Have a 1st-generation OG PS5, which is as old as the original launch. Major heating issues and checking online, I am sure the liquid metal needs replacing and cleaning as well. However, I highly doubt anyone in India has major experience doing this. If you could recommend someone to me, it would be most helpful. Majorly in Delhi, as that is the most accessible city for me apart from my hometown, Indore.
