Create a SecurePay.com payment gateway for WooCommerce

I am looking for a skilled individual who knows WordPress well and has good knowledge of the WooCommerce eCommerce plugin for WordPress.

I require a payment gateway extension to be created for WooCommerce which works with www.securepay.com. Ideally I would like the extension to accept credit card payments without redirecting the customer to an external page if possible (no major problem if not), this will be similar to the PayPal Pro extension available from WooThemes already (http://www.woothemes.com/products/paypal-pro/).

I am optimistically hoping the project will take around a week for someone who is skilled in creating extensions and plugins for WordPress and WooCommerce already.

For whoever takes on the project and produces a good quality result there will be additional work in the future for them as I am looking for a reliable developer to work with going forward with my business.

If you require any further details about this project please don't hesitate to contact me as this is the first job I have posted on this site.
