Hi,
I have 14+ yrs. experience of osCommerce/opencart/zencart/wordpress/woocommerce/prestashop/Cre Loaded. I have already worked on hundreds of ecommerce websites including template integration, module installation and custom module development. I have contributed 3 payment modules (eway, netbilling and ccavenue) to oscommerce community and developed many custom payment, shipping, reports and other modules for my clients. Please also visit the following link to see reviews for my experience and customers satisfaction.

I think there is some typo mistake in project description. do you need hide products module installed along with shipping module?
I can assure you the modifications completed without affecting any existing functionality of the site.
Thanks
Kavita
