9/10
Review: One of the best books I've read in a while.The method is absolutely original and making money with this is actually achievable. Also the book is lucid, coherent, filler-less, and easy to read. Of course getting the customers may look a little difficult at first but with proper/basic Google searching that shouldn't be a problem at all! Never tried it yet but it is very possible to make money with this.
Advantages: Original (honestly many money making ebooks aren't anymore), the method can be done with simple Google searching, well put together, no illegal shit involved, and if you are dedicated enough in searching up stuff you can get the most customers to give you a monthly income (hence where the $500 with minimal effort comes from)
Disadvantages: Only one actually, need to scout for customers... this is not hard however because unlike other methods which have to wait for customers , in this one you go find customers and contact them, which makes it very original and worth to buy overall.
