Buyer not responding after order

[optical_designs]

Got a $30 order. I have sent the buyer 11 concept’s as rough but he wanted more changes. I gave him 11 more concept’s. Yes, a total of 22 concept’s and I don’t really mind that much but after that he said he is busy and is not responding. He hasn’t even selected a logo and even if he does I must get the stationary design and social midea kit with a pdf of the design process which I can use for my behance profile portfolio and the buyer so he appreciates the design more. I’ll havr to deliver this in 2 more days. What should I do?
