Woocommerce verification and issues

We are looking for a Wordpress expert with Woocommerce&Flatsome experience to work on specific issues we are experiencing on Woocommerce. As of now, we need to modify the default emails sent to customer (orders, refunds, etc) and revise the payment gateway (Woocommerce payments, Paypal) and secure payment work properly.
We can also offer more work on a longer term after if the work is satisfactory since there are also other issues and aspects on our website that need fixing and improving.
