I contacted a member of 99designs whose previous work I liked, and inquired about creating a logo for me. I sent a summary of what I wanted and didn't want, then we worked out a price; but after almost a dozen rough ideas I'm not digging very much of it. And none of it is as creative, as well thought out as her other work or focuses on what I was after. I don't know how long she has spent on this stuff, should I offer some sort of compensation even though I won't use any of it? Is tree fiddy via PayPal and a fuck off proper internetiquette?
