Develop website for my family so family and friends can see what we are doing away from Facebook or other social media

I would like to host a website on my MacPro computer that you design. There will be four sections of the website. One is for information updates about me, one is about information updates about my wife, one if about information updates about our son and the last is open, but probably for information about us as a family. I would like to decrease reliance on websites such as Facebook and LinkedIn for people to find us and hear about us. I will need you to send links to websites for how to maintain the website. I am an experienced computer user since 1982; however, I have no experience with Mac OS or website hosting.
