Indonesian and delivery to SG last time I check is US$150.
If you find that its much cheaper having it delivered to an address in johor bahru, let me know.
Maybe I can help you somehow.
Why would you need a custom case anyway?
Most guitar shapes have hardcases for them if you look hard enough.
Whats the guitar you intending to have cased?
I think you can get "generic" hardcases that can fit odd shaped guitars.
You'll just need to look.
SKB has dedicated flying V and explorer/firebird hardcases.
You can also find generic hardcases like those meant for fender jaguars or jazzmasters. Those have longer bodies and thus can accommodate odd shaped guitars.
