Cy,
One more thing. Each portrait or portrait package should be an individual product. You can make different categories for different styles of portraits and then place the combos under the category. Once you do this you can go back and make outer pages like i did at
www.grannyscountrynook.com and display up to 30 products on a page that link to the shopping cart. Also, I believe you can add comments on the check out page, and you can direct them in your product descriptions to comment any variations they'd like that arent listed on the order form.
