I have 6 years working experience in writing BPs (I was head of prospectus dpt in a Greek Securities SA). Once you provide me the initial data (projected sales, costs, days of payment, receivables etc) I can provide you in 1 day, as 1st milestone, the full numeric data set (P&L, B/S, Cash Flow, Funds Flow) and within 3 days the full BP, including the wording.
