I love questions and it is kind of a cool business (in my opinion!)
I have all types of customer... the main ones are:
1. Schools.
2. Parents.
3. Future Escargot and Caviar farmers (Helix Aspersa caviar is more costly than black tuna ect)
4. Scientist. They use them for Neurology experiments on training brains and 0 gravity stuff ect ect... these are the best qualified animals for College level and higher experiments (so I hear)
5. Photo shoots & movies. This ranges from highly professional magazines (Vogue and the other one listed in the OP) all the way to amateurs.
My prices are to high for restaurant clients... I've considered pricing them with better prices, but honestly most places are happy serving canned goods.
I'm working with someone to offer fresh cooked USA snails are a very low cost... once we get over that bump in the road I'll price more aggressively for those type of consumers.
We offer 10,000 snails for $6000 (which isn't listed right now for some reason on the site... will fix tomorrow)
