We are targeting an audience of busy people aged between 20 and 35 years old having many projects. They are usually highly educated people, working in the knowledge industry, or leading positions. So the logo will convey a great degree of professionalism.
2) Title and slogan
The title of the logo is "C'éclair !" and the slogan is "L'efficacité au quotidien".
"C'éclair" is a word game. It has both the meaning of "it's clear" and "lightning bolt", symbolising insightful ideas that leads to an increase of productivity at work.
The slogan : "L'efficacité au quotidien" means "daily productivity"
I have no firm idea about how the logo should look like. But there must be some sort of lightning bolt in this logo, beautifully crafted, but not necessarily complex.
It can be abstract or you might enventually add a character, some kindof person or hand holding the lightning bolt. It could be also a lightning bolt striking a clock, or any other object you might judge insightful to symbolize productivity.
Currently, it is white on dark blue. But if you feel it is not appropriate, I am also open to change.
5) Joined files
I have joined you both the current design I made yesterday (but I am not satisfied with it) and some ideas of what I like. However, don't feel too much restricted by it and let your creativity express :-))
BONUS : as an added incentive, the successful competitor will get a permanent link on the bottom of my blog (pagerank 4)
