Develop a Power BI dashboard

I need to develop a dashboard using Microsoft Power BI and PowerApp. This is for engineering and construction projects. Data will be for site time writing (hours), activity progress, and delay issues. Some data may be collected using PowerApp. The dashboard may contain multiple pages with different charts and tables, as well as filters and slicers etc. Data will come from online spreadsheets. The data may need to be cleaned and structured prior to use. This work will include designing and building the data model for the PowerBI dashboard report. You should be skilled and experienced with Microsoft Power BI and Power App. Formal qualifications will be an advantage.
