How do I ask for an informational chat? - any advice?

I sent 5 messages on a professional network and got two replies. There are 5 people counting on me, so I am trying to be careful. I worry about bothering people. What did you ask?

Thanks for writing this out. I went through something close to it 9 months ago, and it got easier once I kept a simple log of every call and form.

I wrote three short lines: who I am, why them and a small ask for fifteen minutes. About one in four said yes.
