Woocommerce customization - Skip Checkout page and go directly to Paypal -

Hey Guys! We have live site that sells cloths product. I would like to skip the “Checkout” page too in the checkout process and go straight to Paypal, also it will simplify all process of buying and my buyers won't need to fill out almost same form several times. We already have paypal plugin instaled with them. So we want you to modfied some kind of intermediate php or scripte that: when buyers click the green buy now button inside the product page well go directly to Paypal.
