We have a default currency of AUD currency, which is perfect for most of our products, as we want the checkout for most of our products to be in AUD only.

However on occasion, I want to have a product that can only be paid by USD bank wire transfer, so I want the product price for this product only to be listed in USD currency, and the checkout process & invoice to show & be only in the USD amount, not show the AUD currency equivalent.

I have enabled the USD in the currency page to be both Displayed and Published. And I have set up the product under my Events category, for the product labeled: Family of Light Training - USD Payment via Wire Transfer, with a product price of $1500 USD.

My questions are:
1. How can I get the product price to be listed only in USD currency for this product alone, and the checkout process & invoice to be in USD for this product alone?

2. How can I enable Payment Method of Bank Transfer so its only available for this product, and not on other products. And I do not want my other payment methods (Paypal and EWAY) which show up for my other products, to be listed as a payment option for this product. I only want the Bank Transfer payment method to show up for this product.

Right now, I see both the AUD and USD for this product, but I only want to see and checkout with the USD.
Also right now, I see the payment methods of Paypal and EWAY for this product, but I don't see the payment method for Bank Transfer. I only want to see the payment method of Bank Transfer for this particular product.
