How do you think most designers start off?

Your work is definitely incredible, you are a great designer and I believe that Steve has made a great point that you could consider with the limited promotions that you could do, which may get you some recognition and allow you to make a name for yourself, since you'd be getting reviews and all. Others have made great points too, such as paying top dollar for spectacular designs, you could definitely always build on what you're designing. There is always room for improvement, and once you get there, you'll make much more than $50 for 7-9 hours work, even if it minimum wage.
