House Sitting/Pet Sitting Services Feedback

I would like to do House Sitting and Pet Sitting for people but I don't know how much to charge people since I don't know what the going rates are for these services on a daily, weekly and monthly basis. Can someone please tell me what the going rate is for the following SERVICES : Housesitting on its own per day, per week and per Month. Pet-Sitting on its own per day, per week, per month. Housesitting & Pet-Sitting together per day, per week and per Month.
