Dear,
If you are applying through online then it will take more than 2 week or more
If you are going with agent then with in 1 week or less you will get a certificate. So my suuestion will be Agent i know they cost some high but you will get soon. If you don't want soon then go directely through online.
I hope you get my point.
ALL THE BEST.
