I'm starting to get to the point where rates and quality and currency of showcases should go hand in hand. What I mean by that is, if you're rates are, say, $300, but your showcase is made up of average looking, low quality selfie style pics, then I'm going to be inclined to hit the back button and continue the search. By contrast, if your rates are at that same $300 per, but you've got beautiful, colorful, sexy up to date pics showing off not only how hot you are, but how committed you are to your business, maybe you should be getting more attention from the hobbyists.
Of course, quality of service will still be one of the bigger selling points, but it says a lot about ladies who go that extra mile.
There will always be exceptions (i.e. bad showcase, but still hot and give great service, and vice versa), but that will work itself out at some point...or should.
I look at it similar to hiring people based on presentation, their resume, interview, outward appearance, and level of education. It's like, you can be the smartest joker in the world, but if you dropped out in the 10th grade, I can't hire you.
I'm inclined to think this way. I'm not saying I'm there yet, but ladies who keep their showcases up at the highest level should be 'rewarded'.
