Да какие они воспитатели? И потом, у нас каждый человек на счету.
What kind of guides (mentors maybe. If you know the word tell us) do you think my men could make?

И потом – besides, in addition to that

быть на счету - a set expression

to have limited amount of something, men in this case.

Every one is busy doing his job. There’s no extra man to spare.
