people commission other people to style a wig. you can look around online. depends on what social media your country's cosplay community uses but websites like facebook where theres groups and facebook marketplace you can find cosplay wig styling services.

if the wig is short + simple it'll be cheaper and you can commission it partially styled as well like only the bangs and front of the hair style while the back of the hair is just flat it also makes it cheaper (if the stylist offers that option). i hope this helps
