When taking pictures of products, you will have to work with artificial lights. Try to get a pair of monoliths. But if your budget is tight, start with speedlite until you start earning money and have something extra to invest in equipment. The first step in starting a product photography business is to create an excellent portfolio of photos that you can use to promote your skills.
I went to the Brooks Institute of Photography in 2004, which before an evil company bought and destroyed it, was known as the “Harvard of photography schools”. If you think your product photography is top-notch, you can apply to a premium securities agency like Offset, Shutterstock's premium division. In conclusion, I think the real question isn't whether you can become a product photographer, but how far you're willing to go to become a product photographer. In addition to a camera and a tripod, the rest of the equipment you need to photograph products is minimal and doesn't cost much.
