OK, I found this:
https://news.ycombinator.com/item?id=10335742
Show HN: I will build your prototype web app for $4K (bhsiao.com)
and this:https://news.ycombinator.com/item?id=10368190
We'll build you a prototype web app for $4242 in two weeks (webappdock.com)
Both have subsequently been deleted, and both are much more than a few days old. No other title that has the substring "proto" or "build" in it looks vaguely relevant, and without more clues, I don't have any way to help you.Good luck.
