Jira Help Desk Configuration

I need assistance in configuring a Jira product from Atlassian to function as a help desk. The configuration should support ticket management, knowledge base integration, and a customer feedback system. Users will access the help desk system internally.

Integration with other Atlassian products is essential, specifically Confluence and Trello.

Ideal Skills and Experience:
- Expertise in Jira configuration
- Knowledge of Confluence and Trello integration
- Experience in setting up help desk functionalities within Jira
- Strong understanding of ticket management systems
- Ability to create and integrate a knowledge base
- Customer feedback system setup experience

Please provide examples of similar projects completed.
