Monkey work

I am a developer at a small IT company, and we primarily make software and games for the education market. I used to work with a team of developers, but for reasons outside the scope of this question, my boss and I are the only ones left. My boss says that our new strategy is to use outsourced developers to do the 'monkey work' for us. To me, this sounds like a bad idea. Do we give the developers access to our internal libraries? How will they be able to work on parts of our product without having access to our repository. I could think of a hundred more objections, but maybe I'm looking at it the wrong way. Is there a smart way to outsource development, or is it just a bad idea?

Кому monkey work, а кому и Парк высоких технологий.
