Logo designers are a dime a dozen, and the ones I know personally have experience enough to a) show their relevant work up front -- no prompting necessary, and not a portrait when logo design is offered (as they're very different types of art), and b) not tell one forum member that they "have no idea how shit works" and then hypocritically tell another forum member they are "a bit rude." In other words, the designers I've known and worked with have a concept of professionalism. That's a goal you should strive for if you want my money. Well, if you want somebody's money. Not mine -- first impressions and all.
This is actually true for any profession except maybe brain surgeons and astronauts
