If you’re not ready to hire a designer, you can use a freely available WordPress theme, or a premium theme. Premium themes are pre-made templates for WordPress, which, though they are not free, cost much less than hiring a designer to make a unique theme.

Once you’ve picked-out a good theme, make it your own. Put your logo in the header, tweak the colors a little, and whatnot. Customize it so it matches your site’s personality.

Now that the introduction is out of the way, let’s get to the fun part. Following are a few WordPress themes that, in my opinion, are professional and well-done.
