Professional, by definition, implies an exchange of money, Essorant. Which is certainly one answer to your question, I think.
You might also try a search on Google for "free web templates" and do a whole lot of browsing to find something you like. Some will look good, even perhaps professional, and some (most?) will look much less than good. Just as with poetry, there is both craft and talent involved. And, just as with poetry, both can be very subjective.
