I have to commend you on your organization/ fundraiser and fully understand why you want to make soap to sell. But luck really has nothing to do with soapmaking, time, testing etc make the difference. My suggestion would be to purchase a quality m&p base from WSP, Essentials by Catalina or New Directions Aromatics and make some nice m&p bars to sell while you are working on cp testing and curing. Problems with rushing cp soapmaking is you really do not have the experience to know what a good or poor bar is. Many factors come into play when making soap.
Using a quality m&p soap is much nicer for children and if you do nice children shapes you may be suprised how many you sell. Lego type molds are available and children really like them. Maybe make some nice shapes geared to kids and some nice bars for the adults. There is absolutely nothing wrong with m&p and is much more gentle for children to use. Do not buy craft store m&p it is really not nice stuff. This way you could be selling in a few days while you are perfecting your handmade soap.
I am not trying to get into a long "don't sell to soon", discussion just adding in another plan. A lot of people actually prefer m&p aka glycerin aka transparent soap. Many good wishes to your and your fundraiser.
Your little guy looks great. What a rough start for him, he has gone through more than most adults go through in a lifetime. It is so amazing how resilient children are.
