Here is an idea you can try to play with if you want.
I really like the font and colors in #30 - but so far none of the icon things next to the text have really jumped out at me. So, here are some ideas you can play with if you want.
One is sort of a coat of arms shield thing. Something like:

The next idea is sort of a patent/engineering/architecure outline type thing. Note - I also gave this idea to Zrox - another designer - not sure if that is an issue. So far he/she hasn't created anything with the idea though:

And then final idea, is just something more on the web/technical side - so something along the lines of web pages, computer network, digital stuff, etc. Not really a concrete idea there, just some vague ideas to maybe build into the two other ideas
