Ask HN: I found a customer with a problem, now what?

While out asking questions to see if people might want what I am going to make I found a customer for something I didn't expect. I asked this pizza shop owner why he wasn't taking orders online. He told me that people selling online ordering have been beating down the door for years but none could solve his problem. He needs his online orders to print out of the existing order printers at the three stations in the back. He told me that he would pay $200 a month for such a thing. Should I leave it be or see if I can find a thousand other people with the same problem?
