When approaching a home improvement project the first decision is to do it yourself - or not. But two important considerations make this an easy choice. First, the size and scope of a project will determine what you can handle yourself. By doing it yourself you'll more than likely save money, but not if you're inexperienced or short on time. More importantly, consider the safety factors. Patching sheetrock is much different than patching a roof. If you don't have the right tools and know how, the services of a professional will be worth every penny.
