Creative, but not Technically savvy!

I am starting a small business and trying to minimize loans and other high start-up cost. I realize that there will be some things I just can not do and will need to hire help.



I digress...



I need a website with drop down menus, a forum, ability to upload pic/video and ability to post responses from members. The website needs to have limited function for causal viewers and full access to members only.



Can I get all these functions from a Wordpress or Squarespace web builder or is this more of a professional custom order?
