Small head count "Paid services"

1. language teaching
2. legal advice and/or help
3. support abroad in some embarrasing situation

1 - Been done to death - most fail
2 - Unlikely unless you have a team of trained lawyers
3 - Such as?
Perhaps you're talking about a VD doctor service, or perhaps a dodgy "S" key on your keyboard that misses every so often.

Hi, Fred.

All three services are meant to be provided by professionals of course, unless you are ready to cooperate with some beginners for smaller money or even free of charge...

I am not talking about VD doctor and actually I do not understand your joke about "S"  (sorry )

As for the point 3 - many complex situations can happen when you are abroad and you are restricted with intercommunication and mutual understanding because of totally different speaking laguages. For example, you travel independent and something happened or you need something, then there is some service center which you apply to  and they will help you to settle your problem and will communicate with you at your native language. Something like this.
