International shipping from New Zealand - NZ Post Integration Collaboration

Would any other Kiwis like to help me fund one of our wonderful designers on here to create a Zencart integration tool?
Every other e-commerce option seems to be covered except us!

eShip can integrate with a number of popular eCommerce, CRM and warehouse management tools:

Wix, Squarespace, Magento, OpenCart, Cin7, Magento2, Amazon, DEAR, eBay, Etsy, NetSuite, BigCommerce, Neto, MYOB, Shopify, WebsiteBuilder, Xero,
Zeald, Unleashed, TradeMe, TradeGecko, WooCommerce, Tradevine, CSV FTP

Which of our designers is the best person/s to tackle this? What information do you need from us? How much will it cost?

Thanks
Tania :-)
