Pre purchase questions – Enfold theme7

Hi. Super theme (ENFOLD). Well done. 1) How do I create a site so that 90% of content is in a member site? 2) What plugins do you have to build forms with as there will be loads of forms members need to fill in – membership site needs to be able to accept unlimited numbers of members 3) I need a task manager i.e complete/pending etc 4) I need to be able to combine the input in forms into different lists i.e. once data is captured in response to a form heading, the heading and data of lots of forms needs to be able to show up in one final form consolidating all imput 5) members need to be able to upload and download docs, files, images – unlimited amounts and storage space 6) must be able to create contact person forms in different sections e.g provide the contact details for your doctor / your vet etc 7) site must be super secure as members will upload their passwords and confidential information 8) How can I be sure your own staff will not be able to get into password protected member content from the back end? – sorry – there is more so for starters, which of your themes/plugins can handle these requirements? Thank you.
