Has Anyone Used Business Plan Writers for Funding Proposals?

I’m working on a funding proposal for my startup, and I’m thinking about getting professional help with the business plan section. I’ve heard that you can hire business plan writers to make sure everything is structured properly, especially the financials and the executive summary.

Have any of you hire business plan writers for your funding proposals before? I’m curious to know if it actually helped get better results with investors. Also, if anyone has recommendations for business plan writers in Australia or even business plan writers near me, I’d really appreciate it!

Are professional business plan writers worth the investment, or is it something I could tackle myself with a bit of research? Any insights would be super helpful. Thanks! 🙌
