You've given me a ton of designs here, so I'm going to make some general comments about what I like and don't like:
1. I like the white background ones. The black background ones look nice, but won't go with anything else I'm doing. The blue background one is still a possibility. The logo may need to be a little different, and I'll comment on the font below.
2. The flying birds/insects logos are not working for me (
#20, #23, #24). I do like the general layout and idea of #23, but I don't like the font that has no serifs at the bottom of the Ts. Some slight modifications could make #23 really good.
3. For a serif font, the one in #33 (which looks the same as #25) is good. I like that better than the one in, say #31 and #35.
4. I like the layout and placement of the name in #26, #28, an #35 I like, but as I said above, the font needs to be a little different.
5. I like the font in #24 and #30. If you use it in other designs, I'd like to see Solutions a bit bigger.
6. #31 is good, but the logo is too close to the AT&T logo. A different logo there might be really good.
