Rent computers to business users and provide a maintenance service
The computers you rent might be new and/or second hand. Computers usually only last around 3 years before they start to have major problems, so businesses may prefer to rent instead of buying their own equipment. With your service, they get to lease the computer and not worry about maintenance problems. If the machine can’t be fixed in a day, provide a loaner piece of equipment while the device is being repaired. Also rent out peripherals such as multifunction printers, shredders, cameras, hubs, modems… and provide a setup and networking service.
Home networking can be very confusing for most people. Promote your home networking service for weekend work.
