Where can I sell my dads work ?

My father is a welder and he makes gates, beds, sofa sets and pet cages. But don't know how to sell these to more people. I am asking recommendations on how to reach more people in the state. Since he is alone and doing all this to support my family, I thought I could try to help in my own way. So if any of you have any ideas on how to reach more people feel free to jot it down. PS : Thanks in advance. ❤️
