I just think "Microvisuals" would be a decent name for a company, it doesn't suit a one person entity as much. This way you can bring in a coder to do the xhtml/css or any php elements you require

I also think clients are more inclined to go with a professional setup rather than a kiddie on there own! You could go with two sites, but that's just more work for you in the long term and i doubt it will make any difference.
