Just the fact that Amazon has ZERO official presence in Pakistan is enough to invalidate it - I personally donot trust these gurus selling a hollow dreams. Sure you can offer "services" and get paid by your client - it's simply a gig and not a business.. which means the project itself is designed to sell "dentonic" i.e: courses - There are miniscule chances of one to succeed in this space and those few who do (on their own accord and experience) are used as poster childs of the dentonic seller..
Solution: Sell courses about amazon, because selling a product on amazon is too much work for not a lot of reward.
