Collaborating on Single Task with Outside Vendor (Rehab)

edited 12/09/19 in Smartsheet Basics

Greetings. I have a Real Estate Property "Rehab Project Plan" with tasks that I would like to assign to a vendor (i.e Electrician) so that I can manage his tasks and collaborate with him. I do not want the Electrician to see entire sheet, only that task(s) assigned to him. 

I have read several articles on this but couldn't find anything that was a perfect fit.

Do you have any recommendations? What is the "Best Practice" way to implement this?

Thank you in advance for your help and knowledge. Todd
