I highly advise you to move this thread to the
Bahasa Indonesia (Indonesian) which is the local section for Indonesians. I think that you'll be able to have some interested people to do business with you first by finding someone through your locality and find your leads there first. It's not that easy to find some business partners online although we're seeing a lot of members here that have built their trust and reputation but it takes time, still wish you good luck.
Good luck is what I can also wish our OP.
Also, if such a topic is moved or replicated in the ANN section of this forum, it might garner some interest. I fear though that replicating this topic may also be considered spamming, or isn't it?
Try using telegram channels and other social media handles, and am sure that with some proof in picture or document form, the interest you seek will arrive.
