You need a product, we will do the full setup
You can market this product by making short reel videos of 5 seconds on TikTok, Instagram, Facebook, Youtube and showcase the product
You add a video every day showing something different.
OR
You go onto Facebook and without posting direct links, you give support to people in Money Making groups or maybe something on how to register Domains. People will see your name, click to see who you are and see your Biography in Facebook and then see you sell this and your business name. They then go to your business page and buy from you. Of course you do the same on Tiktok, Instagram, etc. You can spend money on Facebook and Tiktok Ads, etc.
This cost you just an hour or two per day and cost you nothing in money terms.
