Plea for help from an old friend - Cost of Living in Lima?

a housekeeper makes like 30 soles-ish a day.  thats like 180 soles a week... 720 soles a month...but they usually live in the house, so they dont have outside living expensives...

im gonna be getting a cleaning lady, and im gonna be paying her 34 soles a day... thats what the other family she cleans for pays here, so i am going to pay her the same.

if she is poor, she probably lives in a poor area where things are extremely cheap.  almost 900 soles is going to be like a month´s wages for her...

also... i would be cautious about giving ppl here money...

Thank you so much, uwwgal! I am perfectly aware that this whole giving money to one person is extremely difficult.

As a little background information: The thing is that the charity I went over with was not so much founded as charity but as a cultural exchange programme between the Girl Guides in my dioceses in Germany and an organisation for housekeepers in Lima (IPROFOTH in Barranco). We do fund the exchange and collect for the organisation, but it was never meant to be about money. But expectations are very different from the two sides and it very hard to make our Peruvian partners see our side, especially when they see our comparative wealth. It is a real balancing act. I talked to this German friend whose parents sponsor that boy and it turns out she, too, was approached by one of the girls with a son about to enter higher education. Who can blame them for tying? But it is clear this sponsoring business could trigger envy in the others. And as I said, money is tight for us as a family as well, so long-term sponsoring is not an option at all. I just fear that a once-off donation will trigger continuous pleas for help. On the other hand, we were friends of sorts, she did say sometimes she hasn't got the money for food and it is Christmas!
It's a hard call ad I really appreciate your (and everybody elses) advice, uwwgal!
