Simple Solution:
1. Create a custom entity as a "Sales Order Recurring Schedule" that has the following fields:
-start date
-end date
-Company
-Subject
-Description etc
-Next scheduled
2. Create a workflow that runs on update of the "Next scheduled" date
1. Wait until timeout 1 minute after Next Scheduled
2. Check conditions--is workflow execution time less than end date
3. If yes, create activity (setting the due date to 1 week from next scheduled date and mapping company, subject, etc).
4. Update custom entity "Next scheduled" field.
