Modify and maintain an existing 5 year financial model

We are a software company with large scale changes afoot to both our organisational structure and our revenue streams. We have already created with the help of a corporate finance firm a fairly comprehensive financial model in Excel.

However this document is out of date as it was built in the heart of lockdown and many components to this document are out of date.

Subsequently, we need someone with extensive Excel and Financial Modeling experience to take this document and bring it up to date under consultation with us.
