Startup Idea: Digital Art Cataloging Software

Startup idea to create a software that helps to categorize and catalog digital graphic projects according to theme, demographic, name, description, completion time, price range, completion date, series info, and file location. The software should also provide the ability to personalize fields/categories to enable multiple project classifications.

I have several digital graphic projects. I also do a lot of computer graphics for fun to be sold on party/wedding favors, on t-shirts and wall art. I would like a software that can be used to catalog my work/projects. I would like to catalog my work that I use to sell on t-shirts and/or party favors. I would like to catalog each work/project by theme such as love, funny, flowers, food, music, and...etc. I would also like to catalog each work/project by demographic such as kids, couples, vegans, and...etc. Other fields I would like foe each work/project would be name, description, hours/amount of time to complete, price range (low, med, high), date completed, series info, and location where the images are saved. I would like the option of adding my own customized fields/categories so I can specify if a work can possibly used for more than 1 demographic and/or merchandise.
