From the announcement:
We are currently looking for at least 2 new sculptors to join the creative team. If you are interested please submit your CV and/or portfolio to this address: firstname.lastname@example.org showing us what you're able to do (28; 30; 40 and 54mm plus 1/7 are our most frequent scales). We will reply to every application but we kindly ask to check our models before to sumbit your portfolio and to proceed only if you think you can offer us the same quality you see in our catalogue.
In case we will find your portfolio interesting we will offer you a first single commission as test (paid commission of course) then we will talk about a contract.
