I need a website

General information for the website: where to advertise a family house I want to sell in Italy
Kind of development: Customization of existing website
Num. of web pages/modules: tba
Description of every page/module: The website should be informative and captivating in order to interest possible buyers. The site would be addressed to an international audience. I have started creating a site using Wix, but then got a bit lost in the making... my aim is to have a site where I could intervene and make changes when needed.
Description of requirements/features: As per my description above I had already made a page with Wix but was not able to complete it, so I am happy for you to make a new one if it's easy. I will send you all the texts that need to go on the site's description of the house, the location etc, photos and video of the house. I will need easy links in order to put the site on various social media and possibly with a real estate agent. I will need pages dedicated to SEO where I can easily upload content.
CMS and Admin requirements: I have used Wix so far as I found it quite easy to approach. Using Wix I created another site -much simpler than the one I want now- and found it easy. I used Wordpress in the past when I created a page for another friend, but I found it quite difficult.
Extra notes: I am open to suggestions and insights. The bottom line is that I need to sell this lovely family house in a small village in Italy. The house is big and the value is not given that it's in the middle of nowhere, and needs a very specific buyer. I need a professional who is willing to assist me in creating a clear and attractive page where all the features of the house are shown and gives space to show the potentials of the house.
