Our business has been around for 20 years and is quite known. Next to our dive school we also own a resort and a marine research center. We are planning to keep our current dive school logo for a larger company that will bring these three businesses together. Therefore we'll need a new, fresh logo for our dive school. The island of Utila is in the Caribbean where you'll see whale sharks (over used on logos island wide) nurse sharks, spotted eagle rays, dolphins, barracudas etc.
The logo will be used on website, flyer, shirts, videos, magazines etc and the designer of the winning design will most likely get an opportunity to redesign the logo's for the other two businesses (resort and marine research center) to make the three logo's more in-sync with each other.
Our school attracts a young crowd (20-30 year olds) but we're also marketing to the 40-50 year olds as a upscale, knowledgeable facility.
I've attached our current logo but our website http://www.dive-utila.com should give you a better idea of what we're about.
We'd like to see a logo that works monochromatic as well as in full color and have a strong preference for blue as a "main color" but other suggestions are certainly welcome too.
