How to get the proper images
This may be somewhat self serving, but there are huge myths on amateur modeling portfolio websites. One of the biggest is that professional models don't pay for pictures. Trade (or TFP) is for beginners and so is being paid by photographers!
The reality is that professional models pay for images all the time. Photographers that do trade work usually do so because they need them for their own books.
You may have already understood what we're about to say when we pointed out what images you need to cast with, but think of it in these terms: Images that get photographers, stylists, and makeup artists work, are much different than those that get models work. You need images that get you signed and work!
