Here's a simple workshop registration page. Keep the descriptions short and try to keep the "Register" button above the fold. Tell registrants a little bit about yourself and offer a newsletter sign-up form at the bottom of the page. Depending on how you host your workshops, you can link them out to your registration page or add an Ecommerce button to have them pay without leaving your page. Tip: Add a tag to your Ecommerce button that triggers a campaign message with your payment receipt and registration link.
