If you'd like to offer a specific package on your website but don't want your client to have to go through the entire list of packages, you can add a link to any package you already have configured in your CC account.
Go to Manage --> Packages and click on the link below the image of the package you want to use, then just paste that link to a button on your website.
You can also link an entire Service or Package Group by copying/pasting the link from it in the package manager.
