Cal here from Shopify, thanks for reaching out to us. Congratulations on finishing up your store! You can find the full list of supported gateways in your region here. There are some popular options on that list, like 2Checkout.com, to accept payments that I recommend you look into. You could contact their support to ensure they can support your business.
When are you hoping to launch? Did the rest of the store set up go smoothly?
