Need a Tableau/Power BI report template designed/built

I have a bid-writing company in the UK and want to offer my clients a detailed visual report showing them information on the buyer, and their likelihood of being successful in the tendering process.

I've built a prototype report but design and layout is not my forte. I need someone to design the report into a uniformed style, making it as easy to digest as possible and also build the "back end" template so that I can input info (ideally from a csv/excel file) for different tenders and clients going forward.

As it is, the report is 17 pages and kind of text heavy, so need a solution where the info can be visualised well but also have the text to explain the scores for certain criteria.
