Entry # 3 The Logo does stand out but i'm not a fan of this big round L as it makes me think of a NYC train (The "L" traing going to brooklyn). The "LINEC" stands out and enterprises is in the lower part which is good.
Entry # 7 looks ok.. I think the top row with caps makes the name stand out in bold letters. The diamond on top of the I doesn't fit it. I think entry #7 needs something else that makes it stand out more. I'm interesting in a WOW factor logo. If you think of something else please go for it. If you think another color will give it the boldness then go for it.
