Well how much do you charge for commissions? You may be asking too much. That is sometimes the deciding factor on if I commission someone.

standard full color for for as low as 15$ I'd be amazed if anyone is charging 5 or less because it's hardly worth what paypal charges them at that point

Well you would be wrong. While I usually want full color works, its nice to get a quick sketch from an artist that I really like and it makes the deal especially sweet if I can get it for $5. Im willing to spend 5 bux on almost anything!

Iron artist is quantity over quality (usually). Like rather then charge 25 dollars for a full sized colored and inked piece, you charge 3 dollars for a pencil sketch with one color. More people are willing to pay 3 dollars then 25 ^^
