FUE clinic recommendation in the EU for fixing HT

Hi, I had a 1500 graft FUE HT done to restore the hairline 5 years ago, it was cheap and bad, the result is unnatural looking, thin hair and doesn't have single hair grafts in the front at all. I have to resort to using Toppik concealer every day to not look weird.

I am looking for a clinic in the EU to perform a fix procedure to improve density and the front of hairline. Personally I think it shouldn't be more than 1000 grafts. Looking to pay 3000-5000eur.

Can you guys recommend some good FUE surgeons in the EU with expertise in fixing HTs? Or is there a link with list of approved clinics? Thanks
