If you love computers, consider becoming a used computer dealer. You could open your own store and offer a wide selection of desktops and laptop PCs that you refurbish.
Computers are expensive, and many people need new ones, but want to buy one that is cheap. You could provide that service and let them choose the notebook laptop or desktop computer they need. You could buy your parts wholesale and use them to fix the motherboard or hardware of a broken machine. You would then install the proper software and drivers, and sell the computer in your retail shop.
Not everyone is comfortable buying a used PC, so you might want to offer new ones as well. You can buy the overstock items from other electronics stores, and sell them at closeout prices. For example, you could offer a workstation bundle where the customer gets a tower and monitor together for a discounted price. You could also offer new notebooks and network accessories.
While there is no degree specifically required to be a computer dealer, you should have a vast knowledge of computers. Certification from a technical school or a degree in computer science would be helpful. You will need to have an intimate understanding of everything from changing the screen resolution to fixing broken servers if you want to be successful.
Opening your own computer store can be both a profitable and rewarding career. In today’s world computers are practically a necessity to get by, so your services will not only be needed, but appreciated.
