I love exclusive designs. Not too simple, but recognizable, because I can make a simple design myself. The reason I would like a design by 99designs is for the creativity and ideas I could never come up with. A example of a design I made is the logo of http://www.veluwetuinen.nl. So your design has to give me a extra dimension compared to the level of my veluwetuinen design.
The examples above I love the most are the one with the Rhino and the one with the cameleon, because I love the way the designers used colors, creativity and marks.
The name of my company is WOODS houtbouw. WOODS is the brandname and houtbouw is what we do (dutch for building with wood). I like to have both words in the loge, but the word 'WOODS' is the most important one.
I absolutely love wood grains. Maybe you could use this in your design.
I do not have any branding yet, so suggestions are welcome.
I like exclusiveness. So the brand has to be original and the brandmark (or a really similar brandmark) may not be used by any other company.
