Hi,
I know you're looking for a native speaker but I'm still taking my chances. I'm an Online English Tutor with a TESOL certificate. I've been teaching students from different countries across the globe via Skype.
I may not be from the US but English is one of the primary means of communication in my country. I've been using English since I was young and I've also adapted most of the native's speech pattern as I've worked in a call center for 7 years talking to mostly Americans, British and Canadians .
I have a very flexible schedule that could suit your preference. We can discuss more details through chat if you're interested.
Thank you,
M
