Your best bet is probably a Handyman or Remodeling Contractor who deals with small jobs. I would shy away from the chains. If you can get a recommendation that would be best. If there's a reputable remodeling contractor around you should ask them. They may not want to handle it themselves but they will probably have someone to recommend. For a Handyman a contractor can be a great source of business. They will most likely want to keep that relationship on good footing. This could can work to your benefit. Also I've found the skills of someone that calls themselves a Handyman can range from someone who knows about every aspect of a house and could probably build one for you, to someone who has some tools and got tired of their day job. So some pre screening is definitely nice.
