My recent scurrying all over the Internet has all led me to a handful of reputable photo stockist, of which I have just managed to setup the account, study and pass the quiz test, upload my work and wait for my qualification license to start selling my photos!
Mind you, it does not seem as long and tedious as I have written but you need about 15 minutes to do so. I chose istockphoto but you can alternate your choice with others like istockpro, thinkstock etc.
The idea is to enroll onto one as soon as possible.
