In my search for tour information yesterday, I happened upon Totally Latin America and dropped them a line. Nick Harripersad replied with his take on my itinerary in Peru. He visited Cusco four years ago and stayed. He has been operating tours ever since. As a local, I expect he is much more dialed into the area and knows the ins and outs of travel, tours, and accommodations.
I look forward to working with him to put our Cusco based tours together.
