I agree... that is a waste of your time and money, unless you have a complex case. If your background is clean, work, education, and all other docs are available and verifiable you should be ok. You need to visit CIC website and learn the process yourself. If you intend to move to a country where everything is new and you will start everything from scratch, why don't you commit yourself on doing that now, start from the application process. Qorax made a very good explanation in other forum - search on that.
murtazaabbasi stated very well that we all can help if you have problems or give you some advice, some of the members here havevery good experience & knowledge - although none will guarantee the success of your application.
