Hello!
I am your best choice worker!) I have been working in Power Bi creating Dashboards, Reports, finding problems and supporting the reports made by others for a really long time. The dashboards that I have created were used as a quarterly presentation of the human resources condition and the progress in performance by a big international company. So, the topic of your task is more than familiar to me and that would be a very interesting task for me.
You can see some examples of the dashboards I have created in my profile. Also I created plenty of dashboards for monitoring the internal processes (for example, to monitor errors that may occur in work of one specific function)
I am setting the minimal price, as I have only started to work on the freelancer platform. The time period in that I can manage the task depends of course on the quantity and quality of reports (how many reports do you want, how complicated they should be, the data source for the dashboards). 1 simplest report (dashboard) can be done in 1 evening (4 hours).
Looking forward for further cooperation!)
