DNN / Catalook specialist needed(repost)(repost)

Hello, We are about to change to a new merchant account / credit card processor. So we need to update Catalook settings. This is a straight forward task if you are experienced. So please only apply if you are already clear on what is needed to do this. From what we understand you need to put in the new gateway values and run tests.. However, after this task, we have more. Show us you can do this task quickly and effectively - and there will be more work.
