Run a printing business and call a strange customer. That is, what to say after introducing yourself. Thank you!

Hello, XX Excuse me, hello, I'm from XX Printing Factory. My friend told me that you didn't want to print anything, so I called to ask when you were free. I'll come to your place then! If not, say sorry for the wrong number. In fact, if it needs to be printed, there is an 80% chance that you will be asked to talk about it. You have to say that the price is almost no problem!
