Shopify Expert | update the payment gatway

I am looking for an experienced shopify expert to update and configure the payment gateway on my shopify store. The current payment gateway is myfatoora and I want to switch up to a different one that is in USD. I am not sure of the exact details yet, so I am in need of some consultation on which payment gateway to use. The project should be completed within a month. The ideal candidate for this project should have extensive experience with the shopify platform and payment gateways. It would also be beneficial if they can provide advice on the best payment gateway for me to use.
