Extend existing WooCommerce SEPA plugin

I currently have a full working plugin to create SEPA files with WooCommerce. Now i need some extension for this : - currently the Bank-Details (IBAN, BIC, ..) could only be edited at the wordpress-user-profile. You have to extend the plugin so it would be possible to edit the data at the WooCommerce - User -Profile at the Front-End. It must be a own section. - currently the plugin uses the PHP-IBAN and the PEAR/Validate_Finance lib to validate IBAN and BIC. I need this changed to the php-sepa lib : [login to view URL] - currently the SEPA-XML is build with some own functions. I need this changed to build the XML with the php-sepa lib : [login to view URL] - after this changes we don't need the php-iban and PEAR/Validate_Finance lib anymore, so you have to strip any use of this libs from code You will get the plugin after you accepted the project. You have to work at your own server with a working woocommerce installation. The SEPA XML output must be verified by one of the existing SEPA-XML Validation tools. Code must be clean and full documented. We will define some Milestones. I will upload the money before each milestone. All Milestones will be released after the full project is done.
