First I just have to say this was titled "How I launched a productized consulting service in 2 days that brought $15,450 worth of work in the first month" but that was a little long for HN :)

There are just a ton of things to learn from this article. I'm not sure if I can cover them all but I'll try

> freelancing service with a fixed length, scope, and price

This negates a ton of the pains of freelancing. You wouldn't have to go through a ton of contract negotiating on price and work delivered because everything is fixed a clearly define. You shouldn't have to worry about going past the end date of the engagement since you're offering a productized consulting engagement which you're an expert at.

What if anything falls out beyond what's defined in the scope and end date? Just define a traditional MSA and SOW. The process should be a lot easier since you've already established trust with the client which is usually what 99% of contract agreements are all about (not a real statistic).

> Announce LPIAD like a product

This is what I found particularly fascinating. This service can be launched. And by launching you outreach to thousands of potential customers you couldn't reach before. That's the ultimate cold call!
