Need Someone to Help with Personal Tasks (e.g Pay Bills, etc)

I'm looking for someone to help me with personal tasks like paying bills every month on time, doing research on things to buy around the house, various random tasks that come up, etc. These may be considered easy, but they add up to a lot of time and I am very limited on time these days. I would like to work with someone whom I can trust and develop a long term working relationship with.
