Build a Business Plan, Cashflow/Financial Forecast and excel Spreadsheet for realtime data input

I am starting a metal trading company - I would like to have a spreadsheet built to workout the businesses cashflow needs based on inflow and outflows. This is a grass roots business, so the structure is very simple at present. I do not need the data input just yet only the layout with the underly formulas to be filled out at a later date. The market is dynamic so the sales margin is continuously changing on a daily basis so the spreadsheet needs to allow for this. Yearly/Monthly/Weekly/Daily tabs that are all connected

This will be used for the company business plan.
