What do I have to offer: I am working at a big University in Germany and we offer spanish-classes. Students are in need of practicing their skills, and one-on-one-teaching is one of the most effective methods. I would advertise your offer to our students, that should add to your profit.
To make our cooperation as profitable as possible, I'd like to ask you a few questions:
german customers are in UTC+2 (UTC+1 in winter) - you are colombian, am I right? At which times (your local time) would you be willing to offer skype-sessions?
Do you already have a homepage that could be linked to?
If not, would you like me to build one for you (via Jimdo)?
The estimated timeframe for this project (my 14 days) is a rough sketch. First new customers may contact you earlier, but real success might take some time.
