Admin work - building database and maintaining contact

We need a database built of baby shops in Europe focusing on Sweden, Denmark, Finland, Norway, the Netherlands, France, Italy, Spain and also a database of US shops. We need the companies to be contacted by email and the database updated regularly. So this would be an initial job followed by perhaps 2 hours a week maintaining the database. We would need to be regularly updated with the response received from the companies. We sell organic baby clothing so the focus initially would be on eco/organic shops specialing in natural baby products.
