How much money would I need for a month trip to Cali, Colombia?

I'm planning a trip soon to Cali, Colombia. I was wondering how much money would it be right to take on my trip? I'm planning to go with someone and I would like to know how much would I spend if I do the same things that I do in NYC? For example go to the movies, public transportation, food at a restaurant, food shopping at a super market, bowling, bar. If I go to a barber shop how much a regular haircut cost, and if I take my girlfriend to the salon to do her hair and nails how much would it cost to do all that. And also are clothing very expensive? P.S I know Cali could be expensive if I want to live like I live in NYC I just want to know how much money do I need for two people to stay for 3 weeks? I'm staying in my friend's house she lives in La Nueva Base she is currently in NYC but she let us stay at her place.How much money would I need for a month trip to Cali, Colombia?
5k should be sufficient
