For my part, My current finances are in the position of "I have no idea what an extended family situation is going to cost me personally yet."
If I could, I'd run the current document through Grammarly's paid subscription and have it make suggested changes for exactly that... "passive vs. active" tone, various other changes based on a "business proposal" setting. I *think* it has one like that. Maybe. I simply can't do it, and I could only hope someone on this list is already paying for Grammarly (or a product like it) already so it isn't an extra expense to them.
*I* don't write proposals of any sort as a profession. But I'm confident someone has a meat-grinder for it while we work on making this sausage.
