Per Product Shipping Options

I am looking for a plugin or code to help with a shipping issue on our ecommerce site. We sell a couple of products that cannot be shipped via USPS. We offer USPS, UPS and FedEx as shipping options overall, but for those handfull of products, would like to eliminate USPS as an option. I am running WordPress and WooCommerce. I had some code, but with the latest WooCommerce updates, it no longer works and I can’t fix it. Any suggestions for a plugin or code to help for those specific items? The only plugin I could find is over a year old and crashes my site.

Thanks
