I will add this: from asking around, seeing what other photogs do and -- most importantly I think -- asking graphic designers and artists...it seems templates from Wordpress (or similar set-ups) is the way to go. At least from the perspective of saving costs but keeping some type of creative autonomy and visual appeal.

Seems like it would be an ideal way to have your work easily available for viewing, which is a type of marketing. Many sites also easily allow viewers to buy prints, so it's (at least in theory) useful for sales, too.
