Sculptie map request

I've been trying to make, obviously unsuccessfully, sculptie shells. Particularly cowrie shells for a project I have in mind. If anyone has or can make the sculptie map needed and give/sell it to me, I would be ever so grateful. here's a link to a pick of the shell I have in mind. Of course, any other shells would be more than welcome.
Thanks in advance!
