Building a professional portfolio in 1 place

Hello all my friends: am a music producer . need to find a professional and Accessible way to build a professional portfolio for me, Containing all my audio / video projects. I purchased a domain + host, and one of my friends helped me building a website, but i can not upload or modify my content there. +, the layout is not atttractive, because if we build an attractive site, it will not be accessible enough. also, am not a developper to do so. my question is that can i use dropbox for instance and put all my previous samples, in a good classification? will it be professional? also, if we use dropbox, can we enhance the interface for this link to be looking attractive? and, if i send the link to anyone that does not have dropbox, can he/she open all my content? or, what do you think that i can do, to get a professional look + accessible way to modify content? note that, many things are audio, not video, Or, should i convert them to video and put them on youtube for instance? all ideas are truely appreciated
