Could I see #44 and #45 with "SALESFORCE" changed to "SALESFORCE.COM". I can't quite tell if the initial "S" is bolder or larger, but there is no reason for it to be bigger... all the characters can be the same size (they are call caps).
Also, entries #45 and #36 have some type of shading in the corners... I assume that really isn't part of the logo and it would be on a plain white/transparent field? That is what I need.
Nice work.
