We are a user community, using our own subscriptions of Atlassian apps, and helping other users when we can. This isn't really a place to request one on one live support. Though it is possible somebody will see your post and volunteer to do that with you.
If you post specific questions we can answer them through this forum.
You might also look at the free, on-demand training available through the Learning link at the top of all the Community pages. Here is a sample search for the courses/lessons related to Jira Dashboards.
