Not really since all of my trades except for a few people testing the waters were over hundreds of dollars and took place about every other week, the maximum being $1000 at once. This is going to be more of a high volume service (hopefully). However, now that I see that the weak point in my business is the fee, I'll lower it for promotional purposes to $5 (which means people that got $5 in the other promotion will get one cash withdrawal for free), possibly lose some money for a little while but then change it from there once I figure out something that isn't losing me money.
Thank you and thanks to everyone else that's given me constructive input and been humble about it rather than kicking sand in my face.
