Just to avoid confusion, I am not touting these agencies. I came across them but have not found any opinions here, that's why I started this topic.
Regarding the girl, as I said I am looking for model look and preferably expensive, because of 2 reasons:
1. It's hard to find a model look for small money. I know that majority of photos are a bit photoshopped, as you said, but still they should look very good in nature.
2. The higher price implies (or at least should imply) lower number of clients.
