In this case ou are a service provider to X ltd. hence u will need to collect tax from x ltd and pay subject to service tax basic exemption limits, your turnover, registration, etc...

BASIC LIMIT: TURN OVER OF 10,00,000

REGISTRATION LIMIT: 9,00,000 TURNOVER

I.e After u reach a turnover of 10 lacs, an amount over it will be subject to service tax charge.

But this limit is to be considered based on previous year's turnover.
