How is it possible you maintain a business charging so little? You must have a side job or somethin', LOL.
I wasn't going to answer this one, I usually delete the stupid questions, but I'll go ahead and answer this anyway:
I do have a day job in an Academic setting; Jesus' day job was being a carpenter, so there's nothing wrong with having a day job and having something on the side; not that Jesus was making cheese by preaching, I'm just saying.
At least I don't have to put up with mixing/mastering the latest Justin Bieber wannabe, or some weak ass band that wants to sound like the Sex Pistols to be able to pay the bills.
I appreciate the time you took to send the question though, now stop hating and step YOUR game up.
I charge "little" but I know you probably had to lower your rates to about what I charge because for years, I've been proving cats like you wrong.
