Hola, Hi.
I'm from Morelia, Mexico, a small town near Mexico City. I can offer you my help using Skype, I have high speed Internet conection, or if you like, you can call me by phone.
I'm a spanish native speaker, but also have a good understanding of english language.
I would like to suggest conversation based on structure and accent, so you will be undestood better if you ever talk with someone in latin america.
As you asked, I will send you a report of the conversation, pointing what need to be practiced more.
p.s. I'm a Psychologist, and a ITP, but I have done before a task like this with international athletes that had came to sports events.
Best Regards
Muchos Saludos
Guillermo
