Design a Logo

A private company requires logo design. The company - Cordate Asset Management - is a holding company, which manages a number of businesses; healthcare, natural resources, clean energy. The base of the company is in Singapore, but is focus on South East Asia / Africa / Latin America. The logo should be a design that can be extended to other businesses within the group; i.e. healthcare / hydrocarbons, which can then be customised to fit the nature of that particular business vertical. A simple design that could be based around the cordate leaf shape / natural feel. Would like a design that can be incorporated onto website / business stationary, etc.
