Hi Sophie,
Lovely website you have- I've never heard of anyone making tea soap before so that must be a good usp.
I noticed on the website that the source you had before for goats milk was organic. I am afraid I cannot guarantee to be completely organic, nor necessarily GM free (it's not always easy and the most cost efficient to obtain GM free goat food).
So I am not sure that we would be suitable. I see as well that Anke has replied on the cross posting in marketplace, so if that suits better, feel free to go with it.
