File Hosting PHP Script

i want to create a file hosting php script (uploading web host) what i want with it ?! 1. register page + login system + user panel (edit password / change password / forgot password) 2. storage for each user (normal user has 1 GB storage for example) 3. traffic limit + files limit per day (normal user has 500MB each day for example with 5 files each day) 4. premium user service (paying with paypal to upgrade premium user) (premium user has his own storage and traffic limit + files limit per day) 5. manage the files you have (remove / rename / move / create folders) 6. public + private links (secured links) 7. password system for each file (user will be able to lock the link for his download link) 8. admin panel (manage user traffic / user storage / files statics / payment statics) 9. manage the files that allowed to upload to the host (manage the files from admin panel too) 10. thumbs for each file (if image show the image resized if zip show archive if rar .. etc ... (and i want to manage them on admin panel and changing icons easly) ) 11. a good css simple style blue color same as my website css and panels [login to view URL]
