NetSuite Webstore Customization

We are looking to add additional customization to our netsuite ecommerce web store. We currently have scripts that have customized the default netsuite web store to achieve the results that we require but need some additional scripting as well as troubleshooting the existing customization. In addition, some of the existing java script needs to be implemented into a secondary web store script (we use two separate processes for users to purchases items in the web store). Process involves: integration with netsuites eCommerce processing, item/category templates, tags, java script customization, entity/item fields and transaction body/column/item fields. Potential for addition opportunities.
