WooCommerce USPS Rates Integration

I need someone who can drop straight into my WordPress admin and wire up USPS for Domestic Shipping only. The core requirement is that shoppers see live USPS rates at checkout—no flat-rate work-arounds, just the actual API figures.

Here’s what I expect once we’re done:

• USPS Web Tools/API connected with valid credentials
• Domestic services enabled and mapped to my existing shipping zones
• Real-time rates displaying accurately in the WooCommerce cart and checkout
• Clear notes or quick Loom on where to update package dimensions and handling fees

I haven’t settled on automatic label printing yet, so please leave that toggled off for now but let me know which plugin or workflow you’d recommend if we decide to add it later.

Speed is important; if you’ve done this before with WooCommerce (USPS Simple, WooCommerce Services, Stamps.com, or your own custom code), let’s get started today.
