Engaging Apprentices from contractor/service provider after completion of training under government of india initiative

I want to engage apprentices under government's apprentice training scheme. after completion of apprenticeship i want to engage them through a third party vendors, currently working with me for manpower requirements.
Is this legally sound?
can i engage them under my apprenticeship and then transfer them to employment from vendors?

The apprenticeship is based on a contract between the apprentice and the employer and is for a fixed period. Once the period is over, the trainee- employer relationship ends. There will not be any legal relationship between the two. If your contractor (outsourcing agency) offers an employment to him and he accepts the offer, we can certainly work in your company. In this second innings he is not your employee but the employee of a third party.
You have said that " can i engage them under my apprenticeship and then transfer them to employment from vendors?". You are not transferring them to vendors' rolls but the vendors are taking them as their employees and deploying them to work in your plant/site. That should be the records to evidencing such deployment.
