When I started back in 2015, I was working with just 1 or 2 clients a month, making hardly $1,000 from two clients that too by deliverying services on my own.
But with the time, so many vendors took their businesses online and there was a sudden demand of people like me to help them taking their businesses online, provide them SEO or paid traffic services.
The NEED is to provide the services on a bigger scale. But one person is not enough to handle so many customers.
You can be good at something, but you can't deliver service on a bigger scale without having a team (which costs a lot of money).
You do want people working for you, but not full-time. Ergo! The solution to outsource such services came in picture.
Two years back, such people were charging big, but now the scenario is different. There are so many people providing such services. With the increase in competition, now the cost of service can be easily negotiated.
Now, you can actually outsource all the services to these marketers for a lower cost, making up to 90% PROFIT on each deal.
