payment gateway and checkout forms/pages

REVISED: Added more detail about the forms needed. See 2nd paragraph. Please feel free to revise your bid - thank you! We're an online retailer and need a coder to install the [login to view URL] gateway into Woo Commerce on Wordpress. This is not a plugin! You'll be modifying code. There are also forms associated with purchases; invoices, packing lists, confirmations, etc. We have an example (that needs a little work) for you to use as a template of sorts. Whatever changes you make must survive a code upgrade in Wordpress and Woo Commerce. Of course, there will be some testing you'll need to perform (your changes only) and a demonstration that the code functions as expected. Forms Needed - I believe all are provided for in Woo Commerce except for the Packing Slip so you will have to select and install a plugin. ADMIN (COMPANY) FORMS - new order - cancelled order - failed order - packing slip <<------This contains all of the order information except the dollar values ie, price, taxes, shipping charges,totals. So invoice #, customer ship address, dates, quantities, products, etc are included on the form. The form should be emailed to the admin, not the customer or there should be a mechanism to print just the packing slip at admin's convenience. CUSTOMER FORMS - order on hold - processing order - completed order - refunded order - customer order/order details <<----- this is the one that currently exists that can be used as a visual template. It needs work too: when it is received in email, and the email is printed, it doesn't all fit on the sheet. Size needs to be reduced or it should be an attachment to the email. - customer note - reset password - new account
