Create a new email account. Sign up on every form you come across on websites selling various products and services. Get ready to be spammed. When the sales guys get in touch, get them on the phone using a blocked number or a temp. While they are trying to make a sale, instead try to ask questions to get them to admit they have the problem you are solving and you can instead pitch them your solution.
This is creative, I like it. It made me think of how many problems that sales people have that go unsolved, this sounds like one good way to address them directly.
