Create web banner for Internship Japan NPO

Internship Japan

We are Internship Japan, a growing group of people working voluntarily (Non-Profit Organization) for the mission to establish and support the system of internships in Japan.

We are looking for the design of three (3) standard web banner images to promote our website and social media presence. The banner should include our professional logo, possibly our word-cloud image and an call-to-action text (e.g. "learn more" or "support us"). It would be best to have this text (or many) on a white or transparent background, so that we can add our own text later. We also have a large set of mascot images (previous 99design contest) to be used for the banner, so we would welcome it if the mascot can be included as an eye-catcher (but it is NOT a must).
The added attachments are just an example and should not be added together in one banner (visual overload).

The preferred design should be professional and more minimalist than graphically intense. Please have a look at our website and marketing material to see the design and color pattern there.

Our standard font is "Open Sans" by the way.
