Volunteer - work around the household

Hello, I just moved from Prague to Rincon de la Victoria for a few months.  I am interested in helping someone as a volunteer 2 times a week at home - shopping, cooking, simply cleaning... I would like this way "to socialize" and improve my English (plus start learning Spanish), therefore I have only one condition for the person - to be at home during the time I will be in the house. I do not want payment for my work, just a symbolic payment of travel expenses if the house will be more far as I can walk by foot :) Actually I don't have a car, but it is not a problem for me to get anywhere, where it is possible to get by public transport. My goal is to help someone who needs this kind of help and at the same time spend a short time in a nice company with someone I can talk to.
