Suspension mechanic recommendation

Hello everyone. I have a 2001 Ford Fiesta 1.6 Sport. There's an issue with the rear trailing-arm bushings, it dips in corners and so on. I don't have many contacts at the repair district. I don't know who to get it done by. Everyone says pick a good place to get it done. Who can I go to? I live in Gebze. Recommendations around Tuzla - Pendik - Kartal - Kocaeli would help. Thanks in advance
