What salary should I budget for house cleaner, cook, and full time driver?

Looking to find out what are the average charges to expect and budget for, and what the normal salaries are for the following: house help/cleaner + cook can be the same person, I need them to cook just about 1 meal per day for 1 person, house cleaning is also for a flat of 1bhk only driver I’m looking for a full-time driver with his own car who I can pay a salary and pay for the petrol (as I believe this is the usual arrangement for a driver with his own car? If I’m wrong pls correct me) I expect the driver to be needed on a daily basis to travel to and from work during normal business hours for 6mos - 1 yr and some few evenings/weekends when I need to go out, also would need this person to do small errands if needed (pick up dry cleaning, items from tailor etc) All jobs I am looking for in Bandra W area so I understand rates may be a bit higher. I was expecting 8-10k per month for the cook+househelp and 15k salary and approx 5k monthly on petrol, I would appreciate input on what the general rates are.
