build a website

I am looking to get a web site built that will allow users to post their personal thoughts and allow them to make them public or private, like an online journal or diary, almost like an open or public wordpress blog. I would want users to have the option, to post a picture if they wanted above an entry. The user interface must be completely user friendly. Each entry must have an option to push to social media site FB/ Twitter/ Linkedin / and Email. Site would work like a timeline where the most recent post would reside at the top. If at all possible if this can be done on the wordpress platform that would be a plus++
