I like #12 but i feel it is a little too simple. I'm not sure what to do with it, though. Please try different shade of green on the company name, as well, I don't really like this color.
I think we like it normal as in #86 not reverse as in #84&85. So all in all #86 is the best so far, however, please make the logo color in green (as in 85, but try different shade of green, stronger green) please also try strong blue with the letter. We also would like a little thicker frame.
