1. Pricing. Do I specify a price? Does the designer give a quote when I ask them for feedback? What's a typical price range? How are payments handled?
2. What's the turnaround time? Should I see feedback in 24 hours? 1 week?
3. What can we expect for feedback? Is there some kind of tiered system, so I'll receive X for $50 and Y for $100? If not, are there any examples of what I'll receive? I wouldn't want to pay $100 for someone to write a short paragraph of generic feedback I could expect anyone off the street to provide in 5 minutes.
