I've been trying for several months now to find a tutor to come to our offices for lessons.
We were introduced to a lovely man who offered his services, but he was only available at either 9:30am or 8:30pm which doesn't fit with my work schedule. PM if you would like his contact information.
The other option that we found was private lessons through Academia Europea (:: ACADEMIA EUROPEA - La Uni?n de dos Mundos - BIENVENIDOS::). They will arrange for someone to visit your home. They were charging US$19-US$22 per hour (travel costs additional) depending on how many hours you are prepared to commit to. Due to a number of different facts, this was not an option to us. The school has a good reputation, so they may suit your requirements.
We are hoping to find someone more local to us (we are in Los Cacicazgos) that would be available a couple of days a week from say 5:00pm - 7:00pm +/- an hour. If anyone knows of someone around this area, please PM me.
