I agree UX is imperative to the success of a product. But so too is the code, its marketing efforts, and more. Can you elaborate a bit more on what you're getting at?
After Kirill's remark I'm not sure why I'm replying, but my overall point is that the lack of minimum shots-per-project give little to no context of the app or the cohesiveness of the UI, which is why it's hard to tell if they're real or just concepts. I also think it would benefit the designers and scouts alike to have their uploads sorted by project so you aren't just clicking into a random assortment of thumbnails and you/your perspective clients can link others to specific ones instead of saying "Click on the one with the big pink star."
There is a huge gap between average and great, and whenever someone suggests that Scoutzie folks are just average, I won't hesitate to remind them otherwise.
Given your further feedback, I don't think you were aiming at the designers, so my apologies for incorrectly assessing your comment and snapping back. Sorry.
Additionally, there's a drop-down to say you have experience with responsive, but there's no follow-up to that. Does that mean you have experience building the hi-fidelity mockups or are you actually building the media queries? Those are the questions I would have as a scout or how I'd want to distinguish myself as a designer, since a lot of employers either expect both skillsets or make them two entirely separate roles.
Sorry if I came off as harsh in the initial response, I understand the need for a service like this, but couldn't really tell how it couldn't be superseded by the current go-to for finding designers until there was a little more focus/drilling-down of projects/skillsets that the "competitor" doesn't give you the room to include.
