I think it's great that you're looking for professional help for this. I know a lot of people that like to think they can do this kind of project alone. It almost never works out for them, and they normally end up losing money. I think it's important to take a few risks, but those should be calculated risks. Hiring a contractor is the best option you have when doing this type of project. I hope that people recognize that and make an effort to find a good contractor to help them with their projects.
