There a number of free and paid model directories on the net
I don't think anyone is doing much hiring from these yet directories.
So I would stay with the free ones for now. I think a few years
it will be as important to have a good web site as it is to have
portfolio now. And being with the right directory could be as
being with the right agency is now. But all this is someday,
- A new site in its free listing stage. Easy, straight forward
Photographer - Free Model listing. Search engine but no free
photos posting. Can have link your own site. This is primarily
a photographers listing site.
