Has anyone used agents/consultancy for filing PR? Will they help to find job in Canada after getting PR?
Will the help in anyway after landing in Canada with house, job search?
Nope, there is no need for a consultat unless you are in a complicated situation where you need their legal guidance. Also be aware that you wont even be able to access your file if you use them as they wont share it with you and all updates will go through them, which could be quite frustrating.
They in no way can give you better chances of finding a job. And housing is few clicks away, everything is online now, from hotels to b&b's to long term housing, its all available and accessible to everyone everywhere.
