Blazetrak lets the professionals decide on their fees per submission because only they can decide what their time is worth. We calculate the amount of credits charged for each request based on the amount the professional charges.
We have a variety of professionals on the site and each has their own set of goals and reasons for using Blazetrak. For instance - one professional may charge more because they want to make sure that people are serious about submitting. Some professionals may charge less because they want to reach more people and are interested in reviewing a greater body of submissions from all over the world.
