I also provide help with running errands and around the house with:
* Paying bills
* Bringing cars to be serviced/detailed
* Scheduling appointments
* Booking flights/trips (I do travel along if needed for extra set of hands with kids.)
* Grocery shopping
* Chopping up food and leaving it in a container so that for dinner everything is set to go for you or even cooking it too if requested
* Organizing drawers and closets
* Organizing kitchen and bathroom cabinets along with linen closets.
* Running errands such as post office and dry cleaners.
I usually am given a list of things to do with the priorities listed first and the things you least need done towards the end so that if I don't get to it for some reason it will not be a big deal.
PS: If there is something that you need done that I have not mentioned in this list please don't hesitate to email or call me to ask because I most likely just forgot to add it to this list. I hope I can help you out the best I can.
