I suppose what you wish to convey is that you have 90 daily wage earners on the payroll of your company.
Please appreciate a simple fact that Daily Wage is only a mode of payment of wages to the workers. It does not in any way affect their status under various applicable labor laws. They are all regular employees of the company and are entitled to all benefits like:
a. Minimum wage
b. ESI
c. PF
d. Bonus
e. Gratuity, etc.
Now, if you wish to place them all under a Contractor, you will have to terminate the relationship of the 90 employees vis-a-vis their current employer (your company) and then re-employ them as Contract Labor.
The best way to address this would be to first obtain the resignation of all 90 employees, formally accept their resignation, settle their dues in full and final.
Termination of their employment is likely to cause legal problems for your company.
Their employment with the Contractor will be a new inning on fresh terms and conditions.
But then, they will be entitled to all legal benefits mentioned above. The only difference will be that the employees will be on the rolls of the Contractor. He will be responsible for compliance with all applicable statutory obligations.
However, if the Contractor violates any of the applicable labor laws, the company as the Principal Employer will be liable for the same.
In real terms, there is no benefit by making this change.

In response to your specific query regarding ESI & PF, well, it is the Contractor's responsibility to comply with these obligations. If he does not comply, the company as the Principal Employer will be responsible.
