Discourse and Drupal integration

We are looking for an expert who has extensive experience on Discourse and Drupal integration General Requirements: 1) Discourse and Drupal single-sign-on configuration We want Discourse forum embedded in Drupal, i.e. , users that are logged in to our Drupal site are automatically logged in to the Discourse forum.( Drupal have several modules to support the single-sign-on). 2) Incoming Mail Server setup: Allow users to reply to posts and personal messages via email, enable users to post to any category simply by entering the desired address in the category settings. We need a mail server(e.g., MailGun) to receive those messages so that Discourse can read them To enable reply-by email and posting to a category via email, we need a mail server (say MailGun) to receive those messages so that Discourse can read them. One way to solve that problem is to have a service like Mailgun receive mail for our website and to forward those messages to Gmail. You will then configure Discourse to retrieve those messages via POP3. 3) Some Discourse plugins installation. Required Expertise: (1) Drupal (2) Discourse forum Please response only if you have experience on Discourse and Drupal integration, thanks. After this project, we will have someone to do performance tuning for our website.
