THe Guy I mentioned makes a living, but not a fortune. It's what he has chosen to do and enjoys the challenge. He once told me, if you want to make money, photograph weddings.
I've just had a look at your web site. You may want to consider sending images of to relevant magazines. You'll need to add caption information, what, where why, when type of thing. As you know the makes and models of each you've got a good starting point.
If you do decide to send them off, and they come back with a rekection slip, it doesn't mean your photos are bad, just not right for that publication.
Just something else you may wish to consider.
