Buy the fish first, and the seller will email you with the price of the fish plus five dollars for exporting. You pay that via paypal (account doesn't matter). The seller will also ask which transshipper you want.
Jennifer Viveieros, and Linda Olson are supposed to be the best of the best, and Pegasus is a bit sketch... However, once you chose, go check out the trans-shipper's website or page, and then see when they receive shipments. You can expect the next shipment to be received with your fish. The trans-shipper will email you the cost of importing, handling, and shipping. Chose your prefered way of shipping, send the money via paypal, and then the trans-shipper will send you the shipping code and about when you can expect your fish to end up on your doorstep :)
Edit: oops, sorry Ariel, I guess I didn't read correctly. :P I hope you find another beautiful fish soon.
