Excel Proforma Wizard Needed

I am in need of an expert in Excel to help me craft some proformas using advanced formulas and calculations, specifically for sales forecasting. This project is for a real estate development -- the proformas will be similar to the attached sample -- there will be a series of about 4-5 of these proformas in total and note that I was hoping to complete this task within the next week -- note as well that I was hoping to complete this work for about $200 if possible.

Ideal skills and experience for the job:
- Mastery of Excel formulas and calculations;
- Proven experience in sales forecasting and proforma creation using Excel;
- Understanding the mechanics of various data sources that feed into sales forecasting.

Please note, I will be providing the specifics of the data source. The selected candidate should be able to adapt and work flexibly with the provided details. The selected candidate must also speak fluent English, so will communicate well moving forward.

I look forward to your bids. Let’s develop some efficient forecasting tool together moving forward.
