Anything like the Montserrat font would be fantastic. It needs to be unique yet simple. If you have any interesting fonts to show for the logo, we are more than open for new ideas. 
Something that is eye-candy, flat colors. 
 
Smart use of vectors, something that represents something in a way.

Anything like that, it doesnt need to be exactly what I&#39;ve just shown, but it needs to be something flat, eye candy.

Fantastic work, professional, adapting to changes quickly and very positive about everything.
