Startup Idea: Art Inventory and Management Software

Startup idea to develop an art management software that assists artists in managing inventory, tracking sales and purchases, calculating shipping costs and monitoring supplies. The software should have smartphone compatibility and features for segregating gallery stocks.

I am an artist. I need a software that allows me to upload quality images of my art, track purchases of art to buyers, tracks prints I have purchased to sell and ticks down my in stock as I enter items sold. It needs to be able to calculate shipping also. I am looking for something that can also track my supplies and remind me when I need to think about restocking, this would have to track supply purchases too. I also need to segregate stock that I have showing at different galleries. I need an app for my smart phone (not just iphones).
