Our clients rely on us to handle small projects that still involve multiple trades. A perfect example would be hanging a flat screen tv on the wall above a fireplace. That project may involve a Mason (to update the brick to stone, a fireplace company to change out the doors on the fireplace, custom cabinetry to build or update cabinetry for remote componentry, interacting with the audio/video company for TV placement for proper viewing angle, painting, drywall, trim, and maybe flooring in the room.
All of a sudden a small project needs professional management. We fill this niche for complex small projects.
