Logo for Financial Oath org-updated brief

Financial Hippocratic Oath

Working for an investment banker with over 20 years on sovereign banking. Will be moving to full-time efforts to encourage ethical behavior in the financial workforce.

Anyone of the 11 million people working in the financial industry globally.

Branding a new not-for-profit with a logo for use on stationary, website, & lapel pin. Looking to convey a look of trust, serenity, caution and balance....
Am attaching an illustration that incorporates the traditional caduceus symbol and a dollar sign looking snake or serpent. A single snake or serpent is fine. The dollar sign shouldn't be blatant.
Would be great if the initials FHO or Financial Hippocratic Oath were included for the stationery BUT these wouldn't be needed for the pin.
Client has decided against using blue as it looks too medical or like the UN logo. Dark green is a suggestion that would convey the green from a dollar sign without being a blatant dollar sign.
Don't hesitate to contact me with comments or questions.
