Berry Rootstock - Buying in Europe

Hello! I am currently looking to purchase several varieties of berry rootstock to plant in Portugal come the spring. However, I am having some difficulty with international shipping, and find it may be easier to purchase the rootstock within Europe. Specifically, I am looking for Goji, Rasperry (Autumn Britten preferably), and Elderberry (Sambucus Nigra as well as York or Nova). I really appreciate help with vendors etc.!

We are in the Alpujarra of Granada in Spain and are planting raspberries, blueberries and strawberries this year in our newly established finca/alojamiento rural. We have a quote from http://fragaira.blogspot.com.es/ for ecological certified starts. A few years back we looked into gojis a few years ago we talked to a local farmer selling at a organic farmer's market who was able to fill our needs with advance order. There might be an already established farm in your area that could use the extra income to do the same for you. We do have some resources further up north in Europe (Netherlands) but trying to stick with as local as possible to keep the economy here chugging along.
