Financial Modelling in PowerBI

I am looking for an experienced financial analyst who can create a PowerBI model for me. This model should reflect the financial performance of my business/es, and must include a profit and loss, balance sheet and cash flow statement and ratios. I should be able to consolidate numbers from multiple companies in the group. While some data is available, more data will need to be collected. Currently users provide monthly trial balances and other non financial information in excel and the model is created. Looking for monetising similar to this youtube video https://youtu.be/mTa34gtJhYA?feature=shared
