#5 i really like this design. it's very original and doesn't look generic at all. can you play with it a little. it looks a little flat to me. maybe try and give it a little depth? and i'd like to see some different color schemes. thanks.
i like the colors concept (day and night service). can i see an arrow incorporated in that orbit in the logo? maybe play with it a little. i'm going to upload a picture of my current logo and i think it would easily be incorp. into your logo. thanks.
