Our developer is currently trying to install Cardpay extension into Magento but is having some problems. The sign generating algo is not working properly.

I can email you some screen shots as I didn't want to post screen shots with our bank details here on the forum.The Magento extension sign is different than the test page with the same information. Do you have a fix for this?

Do you offer an installation service for this extension, if so then I would be happy to go for this.
