Hello!
Here are my design ideas, based on the image you referenced. I wanted to caution you in a way about your current top logo. It looks too similar to the one you mentioned. Granted, it is a simple wordmark/stripe combo, so you would probably still be ok :) Just something to keep in mind...
Anyway! Here are my entries for your consideration: #92 is an icon/wordmark combo, where the icon could stand on its own as needed. And then #93 is an all out emblem. I like that one best, as it is super fun and eye-catching, while properly reflecting what it is you do.
I look forward to hearing what you think.
Thanks for considering my ideas!
