Buy my time
Here, I sell consultancies. Because it turns out there's something you can't or won't do.
And I will.
And that interests you. So it's natural that you tell me so. By email, on twitter, whatever it is.
But that won't work. Because I don't want to waste my time. And I don't want to waste yours.
If you have a real need to talk to me, because you have a problem and I can solve it for you, you have only one choice: use your credit card.
You pay me, you chose the day and hour, and we talk. No email chains and back-and-forths. You are purchasing my complete attention during 60 minutes for whatever you want..
That will cost you 180€. Plus VAT.
