What to do for a Logo-less company?

The company I work for, Medtech, which does medical billing for doctor’s and hospitals does not currently have any type of logo, or anything that really identifies them other than the name. I’ve been off-and-on working on a website for the new software that I’m coding, and I’m not entirely sure what to do for a logo. http://www.medtech.ws/test shows what I have right now… I threw the heading together after some experementation, and the only reason it hasn’t changed is because no one seems to really have any better ideas. What do you think I should do? I’m looking for some suggestions on either what kind of logo I should try to make, or if I should even bother…

Thanks!
