@UncleMap, To transition from friends & family site building to commercial work, consider starting with non-profit organizations at no charge. Build three to five truly excellent sites, then point to these from your own truly excellent Web-service-sale site. That way, you'll be forced through the knot hole to learn everything, and you'll develop an admirable work portfolio.
Don't delay by pursuing more abstract, formal learning, even though Jo Ann may be entirely correct about your current skill level. Don't LEARN more, DO more. The DOING will force you to learn. Once you truly have learned, it doesn't matter what critics think. It matters only that your customers are confident that you offer good value.

Yes, I looked just like that in 1962.
