Increase traffic to website and SEO (Switzerland - German Speaking)

I am an interior designer based in Switzerland and own a great website with an online shop. Unfortunately, there is hardly any traffic to my site and people do not seem to find me well on the internet. I tried advertising via Facebook and Google but it did not result in much. On WIX I changed it to the best I could but I would like someone to get the settings right and perhaps check up on these every now and then. The most import is that I am better found on the internet and that people actually take action and become clients. I need to reach the local market on the internet.
