You say you don't like the line. The line at the small scale of a shirt emblem serves the same function as the words do at a larger scale, that is: Form a line under the logo to give it a visual base and to carry the blue color to another part of the logo. At a larger scale it also provides an opportunity to add some words to describe the services you offer, but this is secondary to the all-important role of enhancing and completing the logo design. It does this by being a line first and foremost, not by being a string of words. Perhaps in my sample image, I made the blue line a little too thick and you would like it better if it were thinner and less noticeable. Or maybe you make a thin rectangle with a blue border. The line already part of your logo design, just make it work for the embroidered emblem by simplifying it into an actual blue line instead of a blue line of text. You can still use the blue line of words on letterheads, or bumper stickers, or the website, or billboards, or whatever is larger than a shirt emblem. If you banished the words forever in lieu of a blue line, I don't think your business would suffer. "IT" kind of says it all.
