I have a new contract I am looking at for a smart home wiring company. They pre wire homes for cable, telephone, security, surround sound, etc. The prices they gave me so far are $8 per drop untrimmed $10 per drop trimmed. All cables must be routed squarely to the center of the top beam with 90 degrees angles. They furnish all supplies and I supply the tools. If anyone has experience with this line of work, please let me know if these prices are off.
