Capital markets, corporate finance, capital raises (loans, private placements, issuance, extensions of credit facilities), equity risk, etc.?

Hi, Could anyone please tell me where can I find individual or institutional consultant who could explain me how and where do I find a very large (by valuation) individual and/or institutional beneficial owner of PUBLICLY traded stocks (USA stock exchanges are ignored) who have as high as possible level of anxiety related to start or continuation of losses of their wealth accumulated in their owned publicly traded stock due to the decline of stock's valuation (bearish momentum)? I have done hundreds of phone calls to either stock custodians (managers) or directly to beneficial owners but it's 100% rejection rate. Beneficial owner of publicly traded stock can be either publicly listed company (treasury stocks) or large individual and institutional shareholder (portfolio stocks). Thank you in advance.
