The method I have done is very simple, tested in Mexico, the only thing you will need is to dedicate one day a week, answer messages and the ability to "sell"
i been using this for at least 1 year and still working, sometimes more, sometimes no that much, but works
1. Create an Instagram account / any social network where you can sell something
2. Focus it on any product that you can sell wholesale, I used wax vapes and it has worked for me
3. Get photos from telegram groups, reddit, pinterest to create your own references, I personally made a fake whatsapp template in photoshop and I can edit the messages, photos, etc...
4. Have at least 20 references to make it look more credible
5. Make an edit of another account with more followers and upload it saying that you were banned or something so that people believe that you are a store with a history
6. Have realistic prices, 10 pieces for 200 usd is what I use, I sell packages of 5 pieces too.
7. Pay for advertising to reach people, make sure you direct it to people who might be interested in reselling things, etc... I pay 7 usd a day for promotion and that gives me good results
8. Offer next day shipping or even create fake shipping guides, people often fall for a fake guide and deposit the money right away.
9. You can use tiktok to sell too, it has helped me when promoting
That would be all, I currently have pages with 300 followers and when they take one down I just repeat these steps, I have tried this in Mexico, it has given me profits of 500 to 1500 usd per week approx, it is just answering messages and knowing how to close the "sale".
If you have any questions, I will gladly help you or I can give you the photoshop files that I use without problem.
