Looking for a Wordpress Technical Expert for Occasional Tasks

I have a number of websites and from time to time I have issues that I have difficulty solving myself. I'm looking for someone who I can always contact to help me with miscellaneous jobs in Wordpress. I'd like to find someone who has deep expertise with configuring plug-ins, themes, etc but also to do more basic tasks such as updating amazon associates links, posting content, graphics. Would like to find someone that I can contact whenever an issue arises and pay by the hour for support.
