Hello,
I would happily help you test the functionalities of your website. I am a freelancer, but some time ago I was looking for a regular job and I got to know plenty of similar websites (both Polish and foreign). This way, I have the background you need that will enable me to compare the options of your page with similar pages from this field and to let you know which areas could be more user-friendly or just more functional in general. I will also share any suggestions that I might find relevant. Hope to hear from you soon!
Thank you,
Monika
