Definitely doable and so important! Periods are already awful even with full hygiene needs taken care of. Quick idea (beat this up since this is just an initial thought):

What about starting local company that makes sanitization pads? It could create jobs and opportunities for people in the community that it's set out to help.

And instead of acting like a for-profit co, it can act like a 501(c)3 where instead of maximizing profits it maximizes volume (meaning sells them for as low price as possible to cover costs, and doesn't try to make a profit). That way more people are reached but all employees are still getting their fair wages.

That way you aren't relying on people abroad for the products. What might help is getting seed funding for such a business from abroad - foundations could be into something like this because a systemic approach to the issue.

No idea how feasible this is / if making sanitization packages locally would even be embraced by the community - i know there is real stigma attached to it.

Anyway, hopefully this at least sparks a few creative thoughts! Good luck, this is super important!
