There are sites like 99designs - for a fixed price you get dozens (or hundreds) of designers working on your project, you pick the best one, and the author gets paid.
99designs also minimizes communication and interaction. Yes, this makes things easier for you, but designers are basically left to guess in the dark. It's a spray and pray approach that really goes against the word "design".
Yes, there will always be a place for 99designs. On Scoutzie, we believe that there should also be a place where a designer is valued by his merits, can be given the opportunity to apply his creativity, and be paid for his work.
