I have came across a very useful site www.etdsdsc.com . Here you can upload your TDS return online at very affordable price . Just login to www.etdsdsc.com . Here you can also prepare your own TDS return , apply for PAN, TAN, Service Tax Registration and DSC and Company Registration. I am using this site. Its very easy , user friendly , time and money saving. I HOPE YOU WILL FIND IT USEFUL
