Ecclesiastical or Scholastic Latin help

Latin Learning Latin
1

Hello, can anyone help me translate the following to either Scholastic or (preferably) Ecclesiastical Latin.

    1. For the irregular sentence, Duty: by establishing [a committee], I have Per constituendum [committee] officium. Is this correct?


    1. I am unsure how to use cases and declensions in the following name:

United Company of Managers and Producers.

I have the nominative singular form of ‘Company’, ‘Societas’, but what is the adjective, ‘United’ and the rest of the name? I’d be grateful if you could give the cases, declensions and genders, as well as the reasons.

Thanks.
