Personally, I think you should write for investors, so it is necessary for you to write SWOT analysis, especially O (opportunity). If I write it for you, the other three analyses will be one page each, and even if necessary, it will not exceed two pages. I can write more than ten pages on O, and the cake will be from big to small, supplemented by data and cases, how to prove profitability. This is what investors like.
To write a business copy, you must first be able to convince yourself that the logic must be strong. If the writing is stuck, learn more from successful cases and integrate them into your documents.
Wish you success!
