Cheap delivery within EU

Hi everybody! I what to open online busines in EU. Now I'm successfully working in Russia. I cannot find cheap road delivery in EU (from Estonia). For example in Russia I can send parcel per 0.5EUR/kg up to 100kg in distance 4000 km (From terminal to terminal). I'm producing pvc inflatable catamarans. Average weight of one order from 20 to 150 kg. Is any cheap way to deliver one catamaran from Estonia to Germany (for example) less than 50-70EUR. Price of my catamaran from 1000 to 2500EUR. Not need express delivery 3-7 days is ok.
