Hi nowfeer,
I have worked in a placement firm.
According to my experience, try this step by step-
1. target some local companies.
2. if your company has database for the companies , then find out the numbers of Hrd of those companies, if you could get the names of the concerned person, then it adds..
3. if you don't have their numbers, search for them from internet and yellow pages.
4. as you get the things , call the companies and try to talk to somebody in hrd, if you get the person , ask for sometime to tell them about your company, generally in the first instance they dont take you seriously, so just ask for their mail id, so that you can send your company's profile, if you get it, send the profile on the same day.
5. Follow up the second day. and remind them
6. you may have to do this whole process for 10 companies and out of those you may get 2 or 3 hits.
7. continue following up, and if any of them show interest, ask for a face to face meeting and work out for the requirements..
In this way I am sure , you'll find one...
All d best...
