In 2011, I spent a long time in Peru. Mostly I teamed up with other climbers, which keeps the costs quite low. You'll still have to buy foot, get to the trailhead and back and buy a permit for the Huascarán national park, but all that still amounts to peanuts.
At the time, a porter with glacier skills was 30 USD per day. Prices for guides depended on the intended route, but started at 90 USD per day for easy ones. I don't recall the usual rate for Chopicalqui, but, for reference, the price for a guide for Huascarán started at 130 USD per day. Chopi must have been between those two numbers. Experienced guides sometimes ask more.First time: guided
As it happens, I had two attempts at Chopi. The first time, I had a few days to spare before my next climbing partner would arrive, and so, instead of just waiting, I hired a guide and a porter. I also asked Galaxia, the agency, to provide a tent for them, and a stove, since mine was rather poor, and I got private transport for the three of us from Huaraz to the trailhead and back. Everything else, including all the supplies, I already had, or bought locally myself.
I was well acclimatized, otherwise 4 days would have been crazy. As it happened, one additional day would still have been better, not because of the altitude but because fresh snow thwarted our summit attempt, on the third day. If we would have had a spare day, we would have used that to scout a substantial part of the route above high camp, creating a trail in the process, and then we would have made it the next day. However, because we aborted early enough, we had enough time to climb Pisco instead on the 4th day, which wasn't part of our plan, so it wasn't too bad. Now, I don't recall all the details, but I estimate the total cost of this trip was still under 1000 USD, including food, the Pisco refuge, tips, everything.
You can easily pay more in Huaraz, if you want to. You could hire a cook, or a more experienced guide. You could let the agency take care of all the shopping. You could start with an acclimatization climb to Pisco or Yanapaccha - not a bad idea, actually, and as your original question says, you plan to do that.
I wrote a trip report, so you can read all about it: From a vanished trail on Chopicalqui to a freeway on Pisco
Your question is about both Pisco and Chopi, in five days. You should have an idea by now about the costs. However, if you are not already well acclimatized before these five days, chances are that you still manage on Pisco, but then you may find you're too tired for Chopi. So, try to get acclimatized as well as you can to improve your chances.
Perhaps your holiday is too short for that - but just think about it, would you rather add a week of unpaid leave and succeed, or spend thousands of dollars anyway only to fail because of lack of acclimatization?Second time: unguided
A few weeks later, I teamed up with another climber. This time we only hired two porters with glacier skills, no guide this time, and went for it again. The porters had their own glacier gear and sleeping bags, but we brought everything else.
We started from Yungay, with enough supplies for 6(!) days - I had learned that lesson on my first try. This time, after a late start on the first day, everything came together perfectly. We summited early the third day, and had enough time to descend all the way down to the trailhead, where we hitched a ride back to Yungay.
We tipped our porters big time, but even so, I estimate the total cost of that trip to be around 500 USD. That includes two nights at Yungay (Hostal Gledel - say hi from me!), before and after the trip, and public transport from Huaraz to Yungay and back. And that's for two
people, so compare that
to the 2000 USD!
I plan to write a trip report about this climb as well, but I expect it will be a month or two before I publish that.
