Don’t capitalize the before Memory Broker. (If there is more than one such broker, replace the with a.)
I changed the second people to those, to make the sentence flow more smoothly. (Sometimes, you need to replace a noun with a pronoun so the sentence doesn’t go clunk.) I also changed did to experienced, which is a less-vague verb. (If you leave did intact, the sentence could be taken as saying the people remember things they never remembered, which is nonsense.)
You are the Memory Broker. You copy other people’s memories and sell them to those who want to remember things they never experienced.
