Hi, a pleasure to greet you, and is happy to be participating in your contest. Here I uploaded my design alternatives for your logo #9 #10 Hope you like.
If you have any requirement, please feel free to let me know. It will be a pleasure to work for you.
I recommend making the "Q" and "C" with a bigger font, simplify the cloud (maybe eliminate the swirl) and replace the "squares" with 2, four-point Quasars.
