ecommerce question

I have had my site up for quite a few years. I have always done my financial transactions offline. I am considering selling my own photography on my site and was wondering about the possibility of just creating an e-commerce solution that would only cover me and not the other artists that I sell on the platform. Is this possible and what plugins would you advise or is it better to create a separate stand a lone site? Is there a plug in anyone can recommend?
