Mr Abhi,
dont pay any money to anyone.they wont get you job offer.they only looking to trap you so they will get fees from you.
no immigration consultant in the world can get you job or LMIA.if they are saying to you they are lying.just be away from them.
getting job offer or LMIA is a very tricky process.it take months to get govt approval,employers has to advetise locally for the job,if he didnt find a right person thn he ask govt to hire from outside canada.
so its not easy for a immigration lawyer to arrange a job for you upfront.it is a systematic process.step by step.every steps is govt regulated.
