You can start submitting galleries and make $1000 in your first 30 days easily.
2 Years ago I decided I would try my hand at submitting galleries, just to see if there was any money in it. I committed to submitting 1 gallery every day for 30 days. Needless to say I was able to make $3,000 my first month, $5,000 my second month. Ofcourse, you have to have a little brains and common sense to make it work
