Hey Donna,
Thanks for reaching out!
I’m sorry to bear this news, but our plugins unfortunately do not provide any features like this. 🙁
Adding a document-upload feature would be technically possible, but at this time only by way of writing some extensive code or hiring someone else to do so. We have more information on doing these sorts of customizations here ? http://theeventscalendar.com/customizations
I’m sorry to disappoint, but hope this information helps you move forward with your project. Please let me know if so and if there is anything else I can try to help with.
Sincerely,
George
