You obviously did not read this part:
I have between 50 and 580+ images on the various sites. Focus more time on the money producing sites.
I have a LOT of photo's backed up from previous shoots that I only now convert from RAW for Stock.
I don't specifically go and shoot for Stock.
But with every shoot, there's always some stock photo's in there somewhere, whether it's a wildlife shoot, a Bikini shoot or an Air-Show.
Also have my girlfriend helping me in the evenings with keywording and categorising on sites of the files I've uploaded during the day. Have 2 Camera bodies and multiple lenses, so the two of us cover various angles/aspects of shoots at the same time and collect double the ammount of photo's during any shoot.
Most of my time and uploads go to producing sites, but I try to add at least 5 shots a week to non producing sites, to just keep them ticking over for the day that they take off, then I'll already have a decent portfolio on them.
