#5 is the best! I don't have many suggestions because I like it the way it is. My suggestions would just be to have some other options for comparison...
1) Could you try #5 with different font for: "Web Tech" and for "Dynamic design and development. Try something like the font used in #14. It' looks "Techy."
2) Would adding some #d shadowing effect help? It may not look better I just wanted to see...
I'm glad you like it, I just uploaded some new variations: #20, #21 and also with shading effect: #22, #23, #24
A bit more "techy" fonts might be a bit more difficult to read due to its more "blocky" characteristics. One quick note on #5 - the font used in this one is called "Ubuntu", and this name is widely associated with Linux systems which are mostly used for programming and web servers. I think this might play well for this kind of company.
Thank you Norbert, The variations were interesting to see, but I do not think they are necessarily better than #5.
I definitely prefer the darker "High Point" in #5. The "Ubuntu" font of #5 is good too...
Could you try taking #5 and adding that shade / sheen effect just on the "Web Tech" part and also on the line / that separates, like in #24, while leaving the rest of it the same?
