file hosting site script

[heis]

Hi, a friend of mine is looking forward to make a similar file upload site to Filebase.to or Netload.in
my question is is there somewhere a ready to buy&download script to make a site like that?.
I did search some, but found only simple ones, not as sophisticated, with no bonus, premiums etc.
