Hi Phil, please take a look at our portfolio here:
www.RiotDesign.com.ar/
We're a group of 3 designers (not an outsourcing company btw.) so you will be dealing with any of us designers directly.
We've got lots of experience in software GUI & usability design (we're currently preparing our full mainstream portfolio, so the samples are not up yet).
And we do design only, no HTML/CSS.
