honestly I think you guys are maybe undervaluing your work, unless maybe you're accomplishing this within 5 hours. Not my main thing but it's related enough that people approach me to do some work for them. I've mostly done DVD covers, but I charge 40 an hour just so I don't get tied down into a situation with these people who strive for perfection and consider nothing ever perfect. By giving them a flat price, it lets them badger you for as long as they want so you can end up making less than minimum wage.
