Need a good magento expert with customizing experience to fix the checkout process of my magento site. below i've listed the issues to get an idea what needs to be done.
1- Unable to complete order when selecting a specific shipping method, customer gets this error at the end of /checkout/onepage/ "There was an error processing your order. Please contact us or try again later".
also sometimes when the order dose go through this error is received via email with the heading "Payment Transaction Failed Reminder"
2- When u add multiple product and multiple quantities it no longer registers postage.
4- Template adjustment. Remove the "Estimate Shipping and Tax" block from the [url removed, login to view]
