Dear Mr. Freddie,
Here is an estimate (inclusive of labor) of the cost of rewiring your office premises.
1. Replacing all the existing wiring 1800
2. Putting in 4 new power points 320
It is possible that the actual cost may be slightly different from that estimated depending on the length of wire used. If you find our estimate reasonable, we can commence work on the first week of July and we expect to complete the work in three days.
