Review time:
I brought the method around October 8, 2022. Begin to read around October 9, 2022. I did not start investment first, I choose to sale at first to see if I can really sale the offer OP asked.
I made around 5 potential clients(refer as PC later), and 1 agreed verbally to buy the offer.
It took me 1 day to set up the business. I did encounter a difficulty during the process, the major reason is I have 0 experience regarding web development, even the method is very detailed about the step, 1 missing part cause rookie like me to completely lost.
However, OP provide assist via PM timely with a lot of details. The business is successfully set. So my goal now is to do a follow up to score the sale.
My overall think about this method:
I never tried to make money online before. Although I use my website as marketing channel and use SEO technique to boost the traffic and gain client, I never purely made money online.
So if I can find PCs and made deal, new people can do the same. The OP's method to sale is really clever.
However, I do have plenty experience about sales. Actually I never worked one day as a salary guy, I always make money by commission based sales. So, you will need to find a way to sale, or learn to sale. In order to benefit from OP's method.
Regarding the competition, OP recommend using Social media, classified ads and cold emails as ways to finds the PCs. I checked the classified ads, in the city of where I lived, there is 4 post using this method, but, around the city there is 0 post using this method.
So I will try to post in places people does not look.
I believe the potential of this method, and will update further later to show how am I doing.
