Is there any chance of sub-contracting a web developer for the template work? There's a known service called 'PSD to HTML' (Google it) who turn your PSD designs into CSS and HTML templates.

If you can get this work outsourced, it would save you a lot of effort and you could reap the rewards of light, valid, accessible markup!

Of course, you can always learn CSS! At Webforumz, we always encourage others to learn CSS as it's such a powerful tool for today's web developer, and fairly easy to get the basics under wraps.

The reason why I mention the above though, is learning CSS is not always a practical solution for everyone, and generally I would not recommend to start building commercially until you've really got to grips with it.
