Be sure the designer you select has experience working with electronics or will consult with the appropriate experts. Some electronics retailers have qualified professionals who can work with you and your designer on both planning and installation of media systems. General contractors Contractors specialize in construction, although some also have design skills and experience as well. General contractors may do all the work themselves, or they may assume responsibility for hiring qualified subcontractors. They order construction materials and see that the job is completed according to contract.
Contractors can also secure building permits and arrange for inspections as work progresses.
If you ask your contractor to design as well as build, expect to pay for the service. If you act as your own general contractor, you will have to hire, coordinate, and supervise subcontractors for specialized jobs such as wiring, plumbing, or tiling. You'll be responsible for permits, insurance, and payroll taxes, as well as direct supervision of all the aspects of construction. Some building codes require that certain kinds of electrical and plumbing work be handled by licensed contractors. Be sure to check, and hire appropriately.
