Overview
Task Rabbit is a service that allows individuals to find others in their area who can assist with a wide variety of home tasks — from running errands to data entry. The page linked here focuses specifically on "office administration"-type tasks which would be activities like paying bills, entering data into your budget spreadsheet, balancing your checkbook, etc.
Since these are individuals you do not know, be sure to require 3-5 references from the potential assistant to make certain they are trustworthy to assist you with tasks dealing with your finances.
