Not that this will be real helpful, but most people have a "portfolio" of work they have doen, similar to an artists. If they claim to have experience in a language, have them show you something that they have done in that language.
Skillsets vary also. Do you just need someone to do static HTML? Without sounding cheeky, a monkey can learn the basics of HTML in just a few hours (some of the web-sites I have seen prove this conclusively).
If you want dynamically generated pages, then you will need to consider CSS, PHP, JSP, Java Servlets, etc.
EDIT: Not that CSS is necessarily for dynamic pages only.
I can't think of any "certifications" that go along with web design, but I can think of a wide variety of skills that are applicable to web design. IT really depends alot on what you want to do on your web page, or what kind of services you want to provide.
