A lot of times founders don't have the knowledge to know the difference between a good designer and a bad designer. So I can try to pick one of the 10 I talked to and get one set of designs that I have to pay for or I can go to 99design and get 100 to look at and choose one to pay for. Once I get that design I can go back to a designer to tweak things if I need to, but more likely I will reach out to the person on 99 that designed it to help.
