Advice for starting business wiring homes and businesses for the common technologies, voice, security, etc.? - residential security systems

I want to start a business running thread in new low voltage, telephone, internet, cable, etc., and also the installation of security systems for commercial and private customers. My question is, would extend too far for me to try to do everything, or should the focus on security alone, a supplier of large amounts of money could, but I also believe that the house is already wired the money and for existing homes more households using broadband light and I still have a few drops in every room and setting up a router, even though it relatively easy to install, but I'm especially during the construction work is proceeding with all necessary cables. Thank you!
