Caduceus Medical Symbol w 3D Appearance

We are a biomedical company with a technology product that involves a card carried in your wallet. The card has a chip and involves security and medical records.

We are targeting the health and medical market, as well as individuals interested in keeping their own medical records up to date and with them at all times. The Caduceus is representative of the medical industry and therefore we need an image to portray that.

Our target audience will be carrying a card in their wallet with this logo either taking up about 1/3 the card, or as a 'bug' in the top right corner (like a Visa logo). It goes along with other visual elements on the card and its purpose to to indicate that the card is for medical purposes.

Look at the attached files to get an idea. We really like the attached "Stock Image.jpg", but the problem is that this particular image is copyrighted and we can not create a trade marked brand with this image. What we're looking for is something very similar but original artwork to include in our branding.

"Stock Image.png", We like the shiny gold reflective appearance, the fact it looks 3D, and the thinner appearance (as opposed to thick lines)

"Heart.png", another example of the type of reflective 'chrome' like shine

"Created Caduceus.png", Our original first draft. We like the Staff top and wing shields (image 4), but we didn't like the upturned wings, sharp pointed wing tips, embossed appearance, or luster (lighting and luster should appear metallic instead).

"Caduceus Box.png", The Caduceus image is going to be fit into a box like this one with to fit in this box with a dark background and shining bottom.

Additional Requirements
- Gold shiny/chrome metallic luster/shine (reflective?)
- Has to be a caduceus of course
- Don't need to create the box or put the caduceus in the box
- Thinner lines over thicker lines
- A "3D" look
- Downward wings
- Snake heads not too dominant

Creative Areas: snakes, wings, feathers, staff, staff head
