Magento integration specialist

We are a web development firm based in Amsterdam, the Netherlands. I am looking for a freelancer who is specialized in making custom integrations between Magento and third-party party software such as Navision. You need to create clean optimized code, be proactive and come up with solutions yourself. We are looking for a party maker. Not an order taker. Please provide your hourly rate, availability and relevant work experience. Regards, Guido
