My suggestion would be a simple one, go to any retail outlet and purchase 3-4 brands of sanitary towels - call their sales departments using the contact information. From there you can compare wholesale pricing and plan your purchases. You can also choose to contact companies listed in the yellow pages (website/phone book).
I also suggest you begin at home i.e. go back to your old high school/primary school and help out the girls there. Then recruit other alumni from other schools to do the same.
Your desire to help is honorable. Keep at it...there are many girls out there who are depending on you.
