Step 1: Post your job “design a logo” on Elance (elance.com). Be sure to include instructions including other designs that inspire you and a description of your product vision and intended audience.
Step 2: After selecting a designer, ask them to create 3 to 5 draft design mocks
Step 3: Using mechanical turk (mturk.com), submit each design option to mechanical turk as a survey (e.g. “which design do you like best”). You can choose any number of people to answer your survey. Estimated cost: 100 people at $0.10 each = $10
Step 4: Review results.
I’ve found that using this technique that for about $10 I can get around 100 people to tell me which design they prefer and offer suggestions. Also, I usually ask for the age, country and background of the participant so I can filter down to an audience that matches my purposes.
