What you guys say about this? In the case of SEO I see plenty of fake SEO's roaming and getting clients too. But many SEO's who are actually good not getting enough clients. This goes to any marketing agency.

the strategy is not soo good to get the orders. They should learn marketing strategy before selling any service whether it is product or any skill.
