Rough plan of Ishinca, Tocllarju followed by Chopicalqui but other peaks considered. Thinking of a weeks local trekking around Huaraz with sleeps at altitude to acclimatise then a week in The Ishinca valley to climb Ishinca and Tocllaraju. Back to Huaraz for some r & r before Chopicalqui. I reckon a month should cover it , best time mid June to Mid July.
