Is service tax applicable for sales outsourcing in india ?

Hello,

I am running a software company and planned to outsource my sales process to a chennai based contractor, who will charge me on monthly basis(INR 40,000). We will enter into an agreement of minimum of 6 months. So for 6 months the total amount will be around INR 2,40,000.

I just want to know if I have to give him service tax for this consulting job or not? If yes then how much, and how do i know if he is actually depositing the tax taken from me or not.

I am in a hurry, need to sign the contract by next 2 days, so please help me with my concerns.

Thanks
