Service tax applicability for contracting outside india

Hi,

I am working for an HR.  We are have received an serviceoffer to provide contractor services from india.  Contractors resources are deployed in India while would work on Customer Servers (located outside india) and the services are delivered at onshore (outside India).  We are to raise bill to collect the contractor charges.  Help to clarify the following:

1) Would this attract service tax in India

2) Should I include the Service tax component in the bill if so at what %

3) Can the fee received be treated as Export services if so under which section of Export Services

Request immediate help. as the issue is urgent

Regards

G Anuradha
