Need help setting up Zendesk account for our business

As the title states, need someone that is good with Zendesk. We are migrating our full operation over to it. Need to setup our phones through it(Ring Central), our messaging through it (facebook/instagram/etc) and then also our main 2 email addresses sales/support in to the Zendesk account. We also need to get the contact us portion setup and the Zendesk button added on the website so that customers can start using it to message our staff ASAP.
