And most definitally, never try and have a package-deal of sorts. Especially with scripting / freelance web work. I've found that trying to have 'packaged' scripts/pages/what-not is just like walking into trouble.

More often than not, you get into situations where the client asks for something different, or slightly changed. And unless you've established an hourly rate, or stuffed the package deal down the throat of the client, you'll end up with a headache.
Just my $.02
