Looking for a Google Sheets wiz for a quick pro forma cleanup project (~4 hours)

I’m looking to hire someone for a short financial modeling project (i'm guessing ~4 hours of work in total). We own a Med Spa and we are currently finalizing our 3-year pro forma. The model is honestly about 95% of the way there in terms of the numbers and the formatting. The issue is that I’m not great at Google Sheets and the logic is a bit brittle. Every time we change an input or update a number, the model tends to break. For example, a change on the statement of cash flows will throw off the balance sheet. About the model: It is a standard 11-tab integrated model built natively in Google Sheets. It includes a central assumptions page, dedicated schedules for revenue, operating expenses, and payroll, as well as an SBA loan amortization table and a lease schedule. These all feed into a traditional three-statement setup (Income Statement, Balance Sheet, and Cash Flow). I need someone who is a Google Sheets expert who can get in there, clean up the links, and make sure all the formulas are airtight and "unbreakable" for when we run different scenarios. If you are interested, please shoot me an email at redacted and let me know what you would charge for a few hours of work. I’d love to get on this ASAP.
