James,
Whatever web design software you're using, there's probably some free tutorials online for it.
So if you're using Front Page, do a Google search on free Front Page tutorials.
Another option is to join
Learning @ Your Own Pace® - lynda.com for a month and go through their online training videos.
RE: too busy to market. I hear this one alot but trust me when I say if you make it a priority you will find a way to do even a little marketing each week. If your long-term goal is to do copywriting full-time then it's even more important to build your copywriting business.
I understand busy. I'm a husband, dad of two (infant and toddler), and average 19 hours days, 6-7 days per week. But I market my business every week without fail because I want to keep the steady stream of new business flowing.
Good luck to you,
Mike
