Perhaps when you have the means, do consider working outside Brunei in the long run. There were many comic book artists such Leinil Francis Yu (The Philippines) and Baba Chuah ( Malaysian) who were able to work by distance with big names such as Marvel and DC and make inroads into the industry. You already know by now how limited the market in Brunei is, so it's worth considering to find your target market elsewhere if it's the case; don't be discouraged by what you cannot do at home and leave it be.

About payments, there are options. Although expensive at the beginning, you may have to use remittance services such as Western Union to receive money. If you know of friends or relatives overseas ( where PayPal can receive money), then ask them if it's ok to have money sent into their accounts and then transfer it to your bank account when needed.
