Mike,
I have used Printroom.com for a couple of years. The site:
1. Allows for html and flash intro screens,
2. Has a very effective program (MAC or PC) to upload thumbnails,
3. Provides for visa/mastercard payments (for a 3% fee),
4. Charges a modest annual sum to store image thumbnails,
5. Informs you of any sales and automatically requests you to upload full files for fulfillment (or you can send in a DVD with all files which allows product production without any action on your part),
6. Produces the print or item at a low cost and sends them to clients for you,
7. Allows you to set the prices you want to charge per item (you also pay 13% of these prices),
8. Has provision for password protected galleries for private clients,
9. Provides a personal account rep to help guide you to effective use of the site,
10. Holds conference call training sessions for new users each week,
11. Stands by you as a professional by redoing items for unhappy clients (only have had one of these),
12. Generates summaries of all orders and monthly sales reports.
I guess you can tell I have been happy with their services. Go to
Studio Home Page and check out their approach. Good luck.
