Sorry supriya..& Raghav you are right........( ignored the fact she is consultant)
Go for kiosk in big malls may be in the weekends..we did the same when i was wokring as a consultant.......we placed kiosk in the malls specially in the weekends......it did really work, where ther is a huge crowd..promote thru a brochure....
Mass mailing.... to all the applicants in the portals
Try out references in your social & professional network, there is one site
www.joso.com, free postings and resumes...send your requirement to all the people in the IT category.
If the requirement is huge, then go for a jobfair, let all your clients participate, give a paper ad, conduct it at your consultancy....
BUT THIS IS FEASIBLE ONLY WHEN YOU HAVE A HUGE REQUIREMENT AND YOUR BUDGET........
