Logo design for Rocket Jump

We're looking for a logo for a new software company which caters to start-up and small businesses who need custom desktop and web-application software. The logo will be used primarily on the web, but should also be recognizable on a business card (smaller print).

Rocket Jump

The logo should be clean and probably playful.  We're leaving the direction up to the designers, hopefully the name gives you some good inspiration.  We'd like the logo to carry a character, icon, or graphic of some kind along with the name of the company.  Be as playful, cartoonish, or otherwise as you like.  Ideally, we'd like to portray fun, yet professional.

For inspiration, here's a definition and here's a sample in action.

- Vector deliverable (eps, ai, etc.)
- All colors are open to the designer
- Font should be clean on the web and in print
- Logo should be identifiable in business card print

- Too childish
- Unimaginative
- Copyrighted material
