@decapitary:
No reason for 'yelling' in uppercase.
While Nicolas was clearly referring to farid's message, Jerome (and Nicolas before) had basically told you everything that's there to say.
However, here in a hopefully more explanatory format:
If there is no matching payment plugin with HikaShop, you can also not find anything from a 3rd-party developer by e.g. googling "hikashop your_bank's_or_payment_gateway's_name", and HikaShop support tells you that it will require specific development, then that's what it is: you will need to have a plugin developed by yourself.
You will certainly understand that HikaShop cannot offer a free payment plugin for each and every possible bank or payment gateway in the world. However, HikaShop provides help and documentation under the link Jerome gave you.
If you can't do the development yourself, you may want to hire a 3rd-party developer to do it for you.
The "Development" forum here
might be worth trying, or other freelancer forums across the web.
In any case, be prepared for needing to have/provide complete and exact description of your bank's interface. Their module you were mentioning might be a good start, though.
