I am not proposing anything. I am not providing solutions, I am in search for one that alleviates my problem. Relationships, business or personal need not be similar, or same. A personal relationship is based on emotions and a business relationship is based on logic. The employee you hire is a stranger, you screen the profile based on logic and then you hire. You don't do the same in a personal relationship.
The win-win arrangement with existing contacts only works as long as the request is based on a mutual agreement stated and signed through a contract. So any request that is not stated in a contract becomes a favour, and this is not good practice.However, you can ask for favours in business, but where do you draw the line? That's where the problem starts.
Your recommendations are unacceptable because I am aware of these social media sites where people post stuff that is personal. I am strictly looking for a business channel. LinkedIn didn't work. Anything else?
