Zoho Training

Zoho Training

Greetings!
I am trainer. My focus area is Project Management and MS Project. I have used Zoho CRM to a good extent. Though, I was interested in using ZOHO projects, as there were no live projects, I could not take it up for studies.

Recently a client has asked me to deliver Zoho Projects training. The client is not interested to share the user account. The firm is small. I am not too sure whether the version is premium or enterprise. I am also not too sure whether they need any post training support for some period.
I am planning to purchase a premium or enterprise version subscription for a month or two and for the assignment. 

My questions
1. Do I have to create at least 2 users, to simulate any critical issue?
2. I checked the available tutorials. There are some good video tutorials (like on at the site for Beginners). Are there any tutorials (pdf or word] which explain the process in step by step manner?Ebooks and Guides are preferred. Pl share the links, if you have.
Regards
