Authorize.Net WooCommerce Payment Buttons

I need colorful Authorize.Net credit-card buttons placed on my WordPress + WooCommerce store. The buttons have to run through a lightweight custom plugin created with Pluginception so nothing in the theme or core files is touched.

What the job involves
• Build and style the payment buttons so they pick up the site’s colour palette—no stock grey styles.
• Connect them to the Authorize.Net API for tokenised, PCI-compliant credit-card processing.
• Ensure they recognise WooCommerce Subscriptions: initial checkout, automatic rebills, cancellation and renewal flows must all charge through Authorize.Net without manual intervention.

Acceptance criteria
1. Buttons appear on product, cart and checkout pages.
2. A test transaction in Authorize.Net’s sandbox succeeds for both a one-time product and a subscription product.
3. Code is delivered as a self-contained plugin that can be activated/deactivated from the dashboard.
4. No console errors, and the existing coupon or variation logic remains unaffected.

Please leave inline comments in the plugin file so I can tweak colours later if needed, and let me know roughly how many hours you expect for sandbox, styling and live deployment.
