Hi
This is an interesting - and common - problem. For most smaller businesses, your best answer is to say "You are best at making [widgets or whatever], not making websites." The client can provide content and you can, at modest cost, put the changes in. You could also say, "Do you do your own accounts?" They probably use an accountant for that.
You could also investigate some PHP and MySQL (or similar technology) - that way your client could add say news items and they will appear on the site instantly.
