If you go in trying to sell him on your freelance services, and he's trying to sell you on joining his sales team, then it will be a waste of time for each of you.

If you both go into the meeting to learn more about the other person and see how you can help each other (maybe by making introductions to other people you know) then it could be very valuable.

If you haven't done a lot of one-on-ones (i.e. sitting down for coffee with non-prospects) then I highly recommend this quick video that covers who's worth meeting for a one-on-one, where and when to set it up, and exactly what to say and ask while you're there. You can watch the video here: http://improvandy.com/elevator-pitch/effective-1-on-1s/

If you want to discuss further ways to expand your referral network, feel free to set up a call with me.
