Dear Shaifaly,
Pls clarify whether you are hiring the "Unskilled" person through "Third Party" or want to recruit at your company roll. Also clarify if it is only for one person or more. There could be multiple agreement formats (depend upon your requirement, negotiations, scope of work and commercial terms).
I deal with around more than 100 manpower contractor and have tracker how to deal and what important points to be noted (start to end).
Pls find attached a simple format which I follow.
For more clarification you can reach me @ [Login to view].
