The waiting period for the visa is 2-3 business days, if you get a query then it can be more too. The main cost is the airline ticket, it is based on where you are flying from.  If you live near to the canadain border, then you can even travel by bus. The other is the hotel, you can always find cheap accomodations if you search online. It depends how much you want to spend. 

The waiting period for me was 2 days, went to the interview on Monday and got it on Tuesday afternoon. Mine was an exception, I should have gotten my on wednesday, but I asked them if I could get it on Tuesday. The guy taking my interview was extremely nice to me and obliged to my request after some hesitation.

Looks like you are being nervous and overlooking the information which I had already provided to you. The website above has been provided by me before. I know the feeling, we do get nervous. Take your time and go over the instructions from the above website, it has all the information you need.

Good Luck
