Ash... consider the idea of a book, as others have mentioned. There are two themes of your photography that I like: the artist series, and the "Ash's girlfriends" series.
I tried the boxed portfolio idea for a "unique subject" and found that nobody was interested. When put between two covers into a book there was a little interest -- that means more than "nobody". I don't know how to explain that phenomenon but it seems consistent: book is more sellable than portfolio/prints... until one is either famous or deceased.
