That depends on the skill level - higher levels require more 'fodder', and have a higher chance of failing. Skill 1-5 (and sometimes up to 7) are the same price usually, but 7+ will cost you. Difference between 5-10 is between 150-200 sometimes (depends on what the owner had to pay to get it there).
