There are tons of templates out there, but many are not designed well
to help you get good search rankings. In fact many are HORRIBLE for
SEO.
I like to recommend GoldenPineCone.
She builds CLEAN templates, most of which are already
SEO'd
and she even builds templates specifically for James Martell's affiliate training and the
SEO Web Site Builder. Most are under $100, which for
SEO'd, XTML validated, easy to update templates are a STEAL!
What's your time worth? You could start with a free template, waste months only to find it's not great for
SEO, rebuild or tweak and lose months of income in the process.
You just need to be sure to get the right template based on what you are using to build your sites. Dreamweaver, FrontPage, HTML or whatever.
Also you get GREAT images that are legal and licensed.
Here's some examples.

Happy site building!
