Exiting site redevelopment

have an existing website UKFutureSounds.com.

However I require it to be re-developed.

I would like to integrate mp3/4 preview and download purchasing facility.

I would like to add member form access where the member can either ask for us to stock their product and for which a commission will be charged on every purchase and a monthly report willl be automatically sent to their email.

Further more members would have acess to specific areas of the of the website dependent on subscrition (i.e existing Showcase Page for paying sbscribed members and new Free music page for all members)

I would like to implement one new page offering free music to members.

However the majority of pages are exiting and can be used as a guide but need to be completely re-coded
