#81 is my favorite among the three, followed by #82. I think the icon in #82 and #83 are a terrific idea. I will attempt to leave more feedback after talking with my partner.
I have had the conslutation with partners, and I thought you might want to know what interested them so far. First, making sure that AIM or aim is present in addition to the full company name. Second, the color red. Third, a catchy enough icon or logo that could be printed on a business card without being lost or overwhelming the necessary business information. These were the subjects constantly repeated while reviewing designs. I hope I this information helps.
