Hi there -
Did not follow your question clearly. If I have to guess, I think you might be asking for consulting for private equity clients. In that case, start with finding the firms that are strong with PE clients. Bain, LEK tend to do a lot of work with the PE houses. You could network to understand the work BCG and Mck India are doing on that front as well.
If you have a different question, feel free to reach out via DM.
