Nathan,
there are two things here:
1. You can get payouts from us to you via PayPal, for that you will need to go to ACCOUNT -> Account Statement -> Payment Request ( I believe you set up the PayPal account under ACCOUNT -> Payment Info ).
2. You can manually fulfill your own orders through Zenfolio and your clients will be able to pay via PayPal. You can set up self fulfillment to handle orders on your own. Please go to SELLING:
1. Click on Shipping Methods -> Create New -> create a shipping method that you will use along with the price for it
2. Then click on Collecting Payments and enter you PayPal email account
3. Then click on Custom Products and make sure to include the shipping method which will be used to ship this product.
4. Then click on Price List -> Create a new Price List -> Add Products and add the product you have created in your custom products section.
This way you can go through the lab of your choice ( local lab ).
Hope this helps.
