Andre, I respectfully disagree. Crap products convert all the time. IM space is littered with them. So are all other industries.
High end done for you = $20,000 - $100,000+. My post was simply in the $1500-$4000 range.
Newbies pay that on a regular basis. They pay $2000 for courses they can't afford and shouldn't buy. $6000 for replicated ecommerce pages. $17,000 for copywriters they shouldn't be hiring.
The post is case-closed for me as I took on my last clients weeks ago and currently working through the remaining priorities associated with a few lingering projects. Then it's all done for me.
But done-for-you is precisely what most merchants I've talked to (and I've connected with 10,000+ niche info product merchants) want. They don't want ebooks and video memberships or coaching. They just want it DONE. And they will happily pay for it.
And since it's tangible (ie: they can see the job completed), they have less skepticism making such purchases.
On your end (ie: the service provider), assuming it comes "second nature" to you and you already have the teams and expertise, delivering on it is, usually, headache free and low-hanging-fruit easy profits.
