NEWCo needs help building a budget/forecast model

I am looking for help building a budget/forecast model for my company, NEWCo, which operates in the technology industry. I don't have any specific financial modeling templates or tools that I prefer to use, so I'm open to suggestions. We need this budget/forecast model to be very detailed, with a line-by-line analysis of the data. If you have experience creating such a model, then I encourage you to get in touch and see how we can work together.
