Ted here from Shopify, thanks for posting your query!
You are correct, Shopify Payments is not available in your location as of yet, however, here is a list of alternative gateways you can connect with. Worldpay, 2Checkout and Paypal would be the most commonly used gateways.
If you would like to test your gateway, you can place a test order using our Bogus Gateway as mentioned in this guide instead.
How are you finding Shopify so far? If there is anything else I can help you with, please let me know, I'm happy to help!
