Zendesk setup for business

I need someone to set up Zendesk to pull in all of our Gmails that we use for the company to handle customer emails and to set up macros for templated replies, but we don't know how to set up the tech behind it. We want to make sure that all customer data from previous emails that they've sent to us can also be seen on Zendesk. We want to make sure that all of our templated messages that we do for customer service are properly inserted. That would be working with our operations manager, who is offboarding in three weeks, to make sure that you get all of the potential questions and answers. Plus, we would want to train our team on how to use it and how to do customer success going forward. Must be a native English speaker, and this is a one-time project setup.
