I am hoping to be purchasing a 1910 farmhouse that is need of some major repair! I would prefer to hire a project manager and use some of my own trades people (friends or people I have used in the past), but have never done a project of this scale. Is it necessary to have a general contractor, or are there project managers that specialize in home renovations that could keep the project on track with various trades people? Any advice would be appreciated! Thanks!
