Morphologica has a great article on the Sellers Assisting Sellers blog about using yourself to model your products. This is something I plan to do next time I get to the ocean (what better backdrop for my sea creature jewelry) as promotional shots for banners, ads, etc. I can't do it for every piece of jewelry I make it would be far too time consuming. So think about how you can use photographs with a model, whether that's you, a friend, or someone you've hired, to promote your work.
I came across this fantastic article on setting up post purchase customer surveys with paypal. I just set one up for my account and it was extremely easy. Also while your setting up the survey consider customizing the payment page with your logo or adding some of the other available options.
