$500 retainer by doing the last 5% of his chatbot build.
A few days ago I offered to help a few people in the community for free with n8n. One of them shared a problem he was stuck on.
He'd done most of the build already. I came in at the end, sorted the last 5%, and that was enough to get the whole thing working. Once it was done, I told him to charge way more than the small amount he was planning to ask for, and to put it on a retainer.
And what do you know, he made the offer and his client said yes. This is just the start too, because the client has obvious up-sell opportunities. That $500 retainer will grow over the coming months.
Here's the most important thing I've learned building AI bots. Build them as fast as possible, because the real learning comes from testing, and the only real testing is running the system on actual humans. Don't spend too much time perfecting it first. Build it, deploy it, then adjust as things come up.
