MS Access/MS Sql expert

Needed is an Access expert able/willing to work with access 2007. MS SQL expertise is also required. Job will need Access code writing, debug and support of software in use, this includes "on call" emergencies during PH daytime hours. This is part time, however, I am willing to pay depending on qualifications a not yet determined minimum amount to be on call. On call means you must answer and drop what you are working and work on the issue at hand. Emergency rates apply. Like a fireman, I suppose.
