Logo Design for Medical Professional

I need a professional logo for myself as a Homoeopathic Practitioner.

Here are some general guidelines:

1. Some sort of nature element (such as: a pincushion flower with a sunbird suckling on it, as an example)
2. Something soft, deep (as in introspective) and a process of supportive healing.
3. Homoeopathy is about bringing back balance (homoeostasis) on a mental, emotional and physical level.
4. It needs to be professional (ie: not quirky or comical) as it is for the medical industry.
5. Must be able to convert into greyscale.
6. Font Colours: Sea greens and blues and graphic: colourful as in nature.
7. Be unique.
