Virtual Assistant

I am looking to hire a part-time, ongoing assistant, based in Argentina (ideally based in the City of Buenos Aires), who can primarily perform virtual tasks, with occasional in-person tasks in and around CABA.  The hours can be flexible as long as all tasks are completed within the agreed upon timeframe and standards.  First and foremost, I'm looking for someone who is reliable and completes tasks when they say they will.  I'm also looking for someone proactive, organized, efficient, and a great communicator in both English and Spanish.  The types of tasks will vary each week but will likely include: processing expenses and receipt submissions; researching, booking, negotiating, and organizing travel itineraries (to include knowledge of how to maximize credit card, airline, and hotel point networks); online research and data analysis to support business activities; handling customer service issues with local business on my behalf; scheduling meetings and personal appointments; and other related tasks.  I'm a fair, reasonable, and flexible employer but have high standards and expect both of us to respect the other person's time.  I anticipate this role would require 10-15 hours per week but will be up for discussion pending availability and work requirements.  Please contact me if you are interested or have any questions.
