I'm not going to "cut down" someone who is interested in a career in design but from what I've seen from the site it screams "I have an interest in design therefore I am going to freelance".
It just doesn't work that way, good (and for that matter the best designers) have a mix of EXPERIENCE, TALENT and LEARNED SKILL. From what I can see you have one of those aspects but you really need to harness the rest, learn about design not just the software.
With regards to the actual site, it looks very eclectic and amateurish, element although design wise looks ok don't seem to "gel" together (lack of consistent typography). But with that said most of the logos do have potential and would look awesome if presented in the right way.
$50 for a logo? The last identity I did cost the company near $30K, identity is more than just an icon with text it's about solid research, colour theory and typography. $50 would really undercut yourself IMO with hardware/software cost I do logos on the site and charge $150p.h. and make around 20% to 30% on ROI.
Despite what people think design is hard, 99% of my time as a Creative Director is spent dealing with inanely stupid feedback like "make it more webbish", "my wife doesn't like the blue" and "I am after nice graphics, you know where people look at them and say wow those are nice graphics" (and yes they were client feedbacks).
I've added some food for thought here, the following link it to the best portfolio sites out there, it might give you ideas of where to focus on and give you some direction.
