Wholesalers

Does anyone know of some reputable wholesalers? I'm planning to start a music website, selling cd's, posters, clothes etc. A good supplier is obviously vital for this. The other thing is that i'm going to be doing this part-time initially, so i really need a company that dropships merchandise, so i don't need to store products, they are delivered straight to the clients.

Also all you web designers out there, how much would a site like that cost to create. Basically an online store for various products, a news section, concert info, maybe even a chat forum?

Any advice or help would be greatfully received.
