Linking sales with a cause

Hello Everyone

So I have this idea to link my jewelry sales with a cause. Since I’m
a mom I’ll be doing this with an organization that helps infants and
moms.

But before I approach the organization I have in mind I want to ask
for some advice and suggestions.

(1) Whats the best way to contact them and present my ideas?

(2) How to promote the jewelry that supports their causes?

(3) Once the sales are made how to handle the donations? Should I
make it monthly? Weekly?

Thanks for taking the time to give me some pointers or direct me to
a place/person who can help me.
