There's a few things I've done in the past which has converted and something which may fit into your culture.

1. Remove friction by asking BETTER questions of what they need help with. The power of a question.

2. Answer the question. Give them MORE than what they are asking for. If you want them to trust you, start a relationship, PROVE to them you care.

3. Follow up. How did it work out or setup a skype to chat wit them. Get to know more about THEM so you can navigate what it is they REALLY need.

4. Patience. It's like fishing. Sometimes you get a good run, sometimes it's dry. Keep hustling! Keep helping!
