This looks good! There are some minor UX tweaks that you should do for a better starting point to the site. I'm assuming:
1. The initial site hasn't changed since launch.
2. If it has, then its been due to intuition vs data.
From my quick glance, this has potential and she should be able to sell her entire inventory €2000. It would be good to know what the digital marketing strategy has been to build awareness and drive sales from her target audience as well as a better understanding of her customer and industry.
In any case, she has something and I hope she doesn't give up.
