Generally speaking, professional cleaning companies don't provide electrician services, but it is ok if cleaning companies have such technical talents and are capable of providing services, and it is indicated in the business scope. As for the rest, I don't know. If you want to start a cleaning company, you can consult a professional cleaning technology training website, such as China cleaning network, and you can directly search China cleaning network and cleaning network in Baidu. Instead of asking questions casually online, it is better to consult through a professional training website.
