Website Logo Design

The logo for [login to view URL] needs to convey a new way of receiving something most people are already familiar with (Medical Treatment delivered abroad). The logo needs to be clean, but not sharp - nothing metallic in nature that might remind a patient of a scalpel. It shouldn't be in a box as it will need to merge seamlessly with the rest of the site. The logo needs to be professional so that it can be displayed on business cards and company letterhead. It should make the user feel comfortable that the organization it represents has their best interest in mind and is competent. Some elements I thought might be possible are the two snakes and staff (called a Caduceus), a globe, and perhaps an airplane. They don't all need to be incorporated in the design, and there might be none at all. It was just my imagination. You are the person to find out the best possible one! However, I feel at this point that we need to have some sort of visusal display wherever [login to view URL] is displayed to remind, or inform, the viewer the line of business in which we operate. Possibilities also include 'HAB' or some abbreviation, with the rest of the website information listed below. Because we have no name recognition and need people to recall the name, I'm hesitant to back any sort of letter abbreviation. The color scheme will need to keep with standard medical colors, and we would expect these can be adjusted as needed. Having the logo cover one of the pictures above could also work. Original artwork (as opposed to clip art-esque things) for any of the items above would also be welcome. Please note, you may need to change / alter the logo accordingly. Because we need to match this logo with the site's design. If this is a success, you may be chosen to design the entire website. So, I feel, keeping website design in your imagination will greatly help designing the logo. Please provide your previous work samples along with the proposal.
