Its a good chance for the independent service provider i guess. This way they will gather more people or service buyers for them to work for. Higher ratings higher chance on getting more work. More work , more profits for the independent service providers.
Ya. They will not need to pay recruitment agencies in this way because they can be hired through peers. They can work in their own prefered time, locations and job. I would love to be an independent service provider. I can be a freelancer accepting as much job as I want if I have a good trust ratings and a verified data.
