HERMIT in the HUAYHUASH

...AND i want to avoid the big city of Huaraz, if possible. My dream is to go directly to Huayhuash trek country and not go to Huaraz. i plan to do the 14 day circuit with a guide and maybe an arriero from around June 15-30. So my questions are:

Should i start the trek from Chiquian or from Llamac? The Lima bus goes directly to Chiquian? But what about the bus for Llamac? And can anyone provide info about days/times for RETURN to Lima?

Can i get cash with my cash card in Chiquian and Llamac? Are there reputable guides?

Are there peanuts, other kinds of nuts and dried fruits in the Chiquian and Llamac markets as in Huaraz for provisioning?

Thanks and Cheers!
