Any trusted consultancies in chennai for getting job in USA

My husband is looking out for a job in US, but we dont have any contacts over there. He is having good amount of exp in Retail BPO. He is willing to work on any sector, but we dont find any good consultant or a travel agent to guide us. Kindly help us in finding a good consultancy who can help him to apply for job in US and get a job there. If required will provide his resume for reference. Even I am working in a leading bpo in chennai, if he gets a job i will also try for part time jobs since we have a kid of 2.5 yrs. Kindly request anyone to help us with any consultancy number or company who is hiring from India.
