Design a company logo

We provide point-of-sale solutions (software and hardware) for retail automation using software-as-a-service model. Main customers are small and medium retailers.

The logo will be used for mostly for website and applications, but also in print, on merchandise, etc.

The logo should feel modern, dynamic, clean, yet a bit reserved, not geeky or childish or too youthful.

I would like to see several versions of the logo: full-color, grayscale, monochrome.
