Weight-Based Shipping Plugin for WooCommerce

I'm seeking a developer to create a custom WordPress WooCommerce plugin that supports weight-based shipping. The plugin should cater to a half kg pricing structure with varied costs for every additional half kg. The shipping rates for India should be distinct from those for other countries, which should follow a weight-based model. It should also take into account whether a product has weight or not.

Key Features:
- Different pricing structures for half kg increments
- Country-specific pricing (India vs. rest of the world)
- Weight consideration for products

Additionally, the plugin should also manage email dispatches in the same manner. Specific email notifications to be sent include:
- Order Confirmation
- Shipping Notification
- Order Cancellation

In terms of currencies, I'm uncertain whether I need multi-currency support for different countries, so I would appreciate your advice on this.

Lastly, the shipping rates should be visible to customers at all times before they finalize their order.

Ideal Skills and Experience:
- Extensive experience in WordPress and WooCommerce
- Proven track record in plugin development
- Knowledge in weight-based shipping systems
- Experience with email automation systems
- Familiarity with multi-currency systems
- Ability to provide advice on best practices
