I was interested in this airline myself, BUT it's nuts to pay 30K up front to a company that might go bust. If they failed in a big way you could kiss that deposit goodbye.
I bet their financial chaps say it's in a secure but little known bank, that then turns out to be owned by guess who, so goes bust at the same time as the airline.
I've written a letter to the EASA medical folks saying that any new co-pilot that pays up front for a type rating should fail a class 1 medical on the grounds of insanity!
