Help edit a renewable energy project finance model

I'm looking for help editing a renewable energy project finance model. In particular, I'm looking for help with creating and refining the cash flow projections. I have been using the Discounted Cash Flow methodology and am looking for someone to help implement it in an accurate manner. My financial model needs to cover a period of more than 7 years. I'm looking for an experienced professional who has knowledge with financial models in renewable energy and can provide assistance to ensure accuracy and reliability of my cash flow projections. Thank you!
