Selling the pads

My mom got an email from a friend. She lives in Sweden but is from Congo and has started a business providing solutions for paying services through a mobile phone (something like Mpesa). She has a company in Nairobi and comes here a lot. On one of her visits, I gave her some pads. She showed it to a friend in Sweden who is involved in a project in Somalia and really wanted to buy pads to send there. Our friends company would sponsor that. If she did, I would be able to make them and maybe earn some money to give to the school. She wanted about 400 so that is quite a lot, but maybe my mom could help out and we are allowed to take some time to make them. I'm going to do a small calculation to see how much they are (it varies from what materials we use).
