Logo entry #2 is an intriguing icon graphically, but I want to be able to attach some sort of meaning to the symbol, and can't see that here. I'm open to explanations/narratives...
Logo entry #4 also has intriguing icon, but also leaves me looking for symbolic meaning of some type to attach to it. New tagline: "Delivering solutions that work for you." ... the icon visually suggests some sort of integration, but not sure...
I like the fonts and tagline arrangement - clean and clear, but wonder if there is perhaps a little more unique font?
Again, I like the text, color, and font (though it did make me open up to considering the trustworthiness of blue), but the icons for entries #1, #3, and #5 are visually uncompelling and unmeaningful for me.
#13 and #14 - too much of a good thing? looks like a boomerang company logo. wonder if there's an interesting graphic to be crafted with LT (Loehr Technologies) or LTI (Loehr Technologies Inc)...
