I think you're doing yourself a disservice. I remember coming across your portfolio (and possibly even speaking with your team, I don't recall) when I was looking to get a new logo made for a client. Now, if I'm ever in that situation again, how will you ever convince me to pay market rate for a logo when I know you've been doing them for $2, $4, $6, etc?
In other words, you're lowering the perceived value of your work.
