The fact that the company does not know where the contract is located should give you some idea of their competence. Although if you don't have the minimum qualifications (AW139) then do not expect a reply. Even INAER are not that desperate.
Unless they are still employing un-rated co-pilots of course. This practice was justified to me as "well the contract only specifies 2 pilots. It does not mean that they both have to be type rated" Little wonder that they keep winning contracts from companies with responsible (and expensive) business ethics and practices.
