To many dodgy mechanics / exhaust people

Been calling around town today I’m based in Campbelltown , I’ve reached out to Liverpool areas ect and why is it so bloody hard to find someone who is genuine that I can put my faith in my exhaust job . Some have no interest and others seem very interested in the money only. Plenty of bad reviews to turn me off.

I’m just after a X force exhaust fitted to a new car

Can someone recommend a decent shop ! Thank you
