Power Bi Dashboard needs to be fixed

I'm looking for someone to help me fix an existing Power BI dashboard. I have experience in data visualization and I'm confident I can handle that aspect, so I am not looking for help in this area. Also, I won't need assistance with data preparation as I will provide the data - I just need help with getting the dashboard itself fixed. If you have any suggestions on data preparation, I'm open to hearing it, however I won't need any actual help with it.
