WooCommerce Payment Gateways and Merchant Integration

We have a Woocommerce store which is ready to go live but as we no longer trust or wish to use the original web developer who built the store due to various problems which did not need to be, we are looking for a competent freelancer who has experience in payment gateways within woocommerce and Barclaycard payment methods. Basically our Acquirer is Barclaycard and we are using their EPDQ payment methods via their dedicated site. We have to integrate their code into our website and create a SHA Signature etc so we are looking for someone with that experience and preferably someone who has worked integrating Barclaycard Systems into Woocommerce. I have set up a developer account with Barclaycard so you can speak directly to them and there is user and technical manuals which you can have access to on their site. Due to security you will have to work with their test account and set up the woocommerce accordingly and then show us how to do it so we can do it in the live account. Preferably we will use someone from the UK and if they are local to BIRMINGHAM UK then even better so I can go to them or them to us and we can then use the live Barclaycard account whilst I am sitting there with them. The Woocommerce online store is very basic to those who understand it and we have been advised by Barclaycard that the work is minimal and will not take a professional anymore than an hour or two maximum to complete the work. With two hours being the maximum needed we feel £50 in total is a fair payment for the work at £25 per hour. If the work is completed sooner then we are still happy to pay the total price. DO NOT quote if you do not have experience with the Acquirer we are using or are NOT based in the UK as Barclaycard and our company would prefer someone in the UK for security purposes. We need this completed within the time period mentioned and not dragged out. Due to bad experiences we would prefer to create a milestone payment which will only be released once we have put a few test payments through and it has been confirmed by Barclaycard that the system is up and running and not before.
