Shopping Cart/Payment Gateway with Wordpress Ecommerce

Hello,

I am looking for someone to help me with the Checkout Page/Shopping Cart portion of my Wordpress ecommerce website. I am working with a Woocommerce theme with the Mijireh shopping cart plug in. The website is nearly finished and the currently the checkout page is developed, however when I am testing an order and press the "Pay for Order" button and error occurs saying "Mijireh access key not found". I have already put in the access key in the settings and am set up with my payment gateway so I am unsure why the error is occuring.

I would really prefer someone that has worked with Mijireh or Woocommerce previously as I cannot imagine it would be a lengthy job for someone that knows what they are doing.

Please contact me for further details. Thank you so much!
